As in any electrical conductor, electric fields in the brain are accompanied by orthogonal magnetic fields. The measurement of these fields provides information about the localization of brain activity which is complementary to that provided by ELECTROENCEPHALOGRAPHY. Magnetoencephalography may be used alone or together with electroencephalography, for measurement of spontaneous or evoked activity, and for research or clinical purposes.
Epilepsies, Partial
Conditions characterized by recurrent paroxysmal neuronal discharges which arise from a focal region of the brain. Partial seizures are divided into simple and complex, depending on whether consciousness is unaltered (simple partial seizure) or disturbed (complex partial seizure). Both types may feature a wide variety of motor, sensory, and autonomic symptoms. Partial seizures may be classified by associated clinical features or anatomic location of the seizure focus. A secondary generalized seizure refers to a partial seizure that spreads to involve the brain diffusely. (From Adams et al., Principles of Neurology, 6th ed, pp317)
Epilepsy
A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy). (From Adams et al., Principles of Neurology, 6th ed, p313)

A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

Nonlinear Dynamics
The study of systems which respond disproportionately (nonlinearly) to initial conditions or perturbing stimuli. Nonlinear systems may exhibit "chaos" which is classically characterized as sensitive dependence on initial conditions. Chaotic systems, while distinguished from more ordered periodic systems, are not random. When their behavior over time is appropriately displayed (in "phase space"), constraints are evident which are described by "strange attractors". Phase space representations of chaotic systems, or strange attractors, usually reveal fractal (FRACTALS) self-similarity across time scales. Natural, including biological, systems often display nonlinear dynamics and chaos.
Predictive Value of Tests
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease.

Physiological properties of raphe magnus neurons during sleep and waking. (1/10381)

Neurons in the medullary raphe magnus (RM) that are important in the descending modulation of nociceptive transmission are classified by their response to noxious tail heat as ON, OFF, or NEUTRAL cells. Experiments in anesthetized animals demonstrate that RM ON cells facilitate and OFF cells inhibit nociceptive transmission. Yet little is known of the physiology of these cells in the unanesthetized animal. The first aim of the present experiments was to determine whether cells with ON- and OFF-like responses to noxious heat exist in the unanesthetized rat. Second, to determine if RM cells have state-dependent discharge, the activity of RM neurons was recorded during waking and sleeping states. Noxious heat applied during waking and slow wave sleep excited one group of cells (ON-U) in unanesthetized rats. Other cells were inhibited by noxious heat (OFF-U) applied during waking and slow wave sleep states in unanesthetized rats. NEUTRAL-U cells did not respond to noxious thermal stimulation applied during either slow wave sleep or waking. ON-U and OFF-U cells were more likely to respond to noxious heat during slow wave sleep than during waking and were least likely to respond when the animal was eating or drinking. Although RM cells rarely respond to innocuous stimulation applied during anesthesia, ON-U and OFF-U cells were excited and inhibited, respectively, by innocuous somatosensory stimulation in the unanesthetized rat. The spontaneous activity of >90% of the RM neurons recorded in the unanesthetized rat was influenced by behavioral state. OFF-U cells discharged sporadically during waking but were continuously active during slow wave sleep. By contrast, ON-U and NEUTRAL-U cells discharged in bursts during waking and either ceased to discharge entirely or discharged at a low rate during slow wave sleep. We suggest that OFF cell discharge functions to suppress pain-evoked reactions during sleep, whereas ON cell discharge facilitates pain-evoked responses during waking.  (+info)

Effect of psychotropic drugs on caudate spindle in cats. (2/10381)

To ascertain whether neuroleptics act on the caudate nucleus itself, the effects of these compounds as well as other centrally acting drugs were examined in relation to caudate spindle and EEG arousal responses (sciatic nerve stimulation) in gallamine-immobilized cats. Haloperidol and chlorpromazine enhanced the caudate spindle at a dose which had no effect on the EEG arousal response. On the other hand, clozapine and a higher dose of chlorpromazine enhanced the caudate spindle, but depressed the arousal response. High frequency stimulation of the sciatic nerve suppressed the caudate spindle. Pentobarbital, biperiden and diazepam, while depressing the arousal response, caused an enhancement of the caudate spindle. Imipramine at a low dose had no effect on either response, whereas at a high dose this drug enhanced the caudate spindle with concomitant depression of the arousal response. From these results, it may be concluded that the enhancing action on the caudate spindle induced by haloperidol and a low dose of chlorpromazine is due to an increase in susceptibility of the caudate nucleus itself. In addition, it is suggested that depression of the activating system is involved in an appearance of the caudate spindle.  (+info)

Arousal from sleep shortens sympathetic burst latency in humans. (3/10381)

1. Bursts of sympathetic activity in muscle nerves are phase-locked to the cardiac cycle by the sinoaortic baroreflexes. Acoustic arousal from non-rapid eye movement (NREM) sleep reduces the normally invariant interval between the R-wave of the electrocardiogram (ECG) and the peak of the corresponding sympathetic burst; however, the effects of other forms of sleep disruption (i.e. spontaneous arousals and apnoea-induced arousals) on this temporal relationship are unknown. 2. We simultaneously recorded muscle sympathetic nerve activity in the peroneal nerve (intraneural electrodes) and the ECG (surface electrodes) in seven healthy humans and three patients with sleep apnoea syndrome during NREM sleep. 3. In seven subjects, burst latencies were shortened subsequent to spontaneous K complexes (1.297 +/- 0.024 s, mean +/- s. e.m.) and spontaneous arousals (1.268 +/- 0.044 s) compared with latencies during periods of stable NREM sleep (1.369 +/- 0.023 s). In six subjects who demonstrated spontaneous apnoeas during sleep, apnoea per se did not alter burst latency relative to sleep with stable electroencephalogram (EEG) and breathing (1.313 +/- 0.038 vs. 1.342 +/- 0.026 s); however, following apnoea-induced EEG perturbations, burst latencies were reduced (1.214 +/- 0.034 s). 4. Arousal-induced reduction in sympathetic burst latency may reflect a temporary diminution of baroreflex buffering of sympathetic outflow. If so, the magnitude of arterial pressure perturbations during sleep (e.g. those caused by sleep disordered breathing and periodic leg movements) may be augmented by arousal.  (+info)

Overexpression of a Shaker-type potassium channel in mammalian central nervous system dysregulates native potassium channel gene expression. (4/10381)

The nervous system maintains a delicate balance between excitation and inhibition, partly through the complex interplay between voltage-gated sodium and potassium ion channels. Because K+ channel blockade or gene deletion causes hyperexcitability, it is generally assumed that increases in K+ channel gene expression should reduce neuronal network excitability. We have tested this hypothesis by creating a transgenic mouse that expresses a Shaker-type K+ channel gene. Paradoxically, we find that addition of the extra K+ channel gene results in a hyperexcitable rather than a hypoexcitable phenotype. The presence of the transgene leads to a complex deregulation of endogenous Shaker genes in the adult central nervous system as well as an increase in network excitability that includes spontaneous cortical spike and wave discharges and a lower threshold for epileptiform bursting in isolated hippocampal slices. These data suggest that an increase in K+ channel gene dosage leads to dysregulation of normal K+ channel gene expression, and it may underlie a mechanism contributing to the pathogenesis of human aneuploidies such as Down syndrome.  (+info)

Intrapreoptic microinjection of GHRH or its antagonist alters sleep in rats. (5/10381)

Previous reports indicate that growth hormone-releasing hormone (GHRH) is involved in sleep regulation. The site of action mediating the nonrapid eye movement sleep (NREMS)-promoting effects of GHRH is not known, but it is independent from the pituitary. GHRH (0.001, 0. 01, and 0.1 nmol/kg) or a competitive antagonist of GHRH (0.003, 0.3, and 14 nmol/kg) was microinjected into the preoptic area, and the sleep-wake activity was recorded for 23 hr after injection in rats. GHRH elicited dose-dependent increases in the duration and in the intensity of NREMS compared with that in control records after intrapreoptic injection of physiological saline. The antagonist decreased the duration and intensity of NREMS and prolonged sleep latency. Consistent alterations in rapid eye movement sleep (REMS) and in brain temperature were not found. The GHRH antagonist also attenuated the enhancements in NREMS elicited by 3 hr of sleep deprivation. Histological verification of the injection sites showed that the majority of the effective injections were in the preoptic area and the diagonal band of Broca. The results indicate that the preoptic area mediates the sleep-promoting activity of GHRH.  (+info)

EEG surveillance as a means of extending operability in high risk carotid endarterectomy. (6/10381)

Some patients who have transient ischemic attacks are denied operation because severe occlusive lesions in other extra-cranial arteries may be inappropriately interpreted as constituting an unacceptable surgical risk, or because the lesion is so distal as to make its removal hazardous. Failure of endarterectomy is usually due to incomplete removal of the lesion or to thrombosis upon the frayed intima. Such lesions require excellent visualization and meticulous surgical technique -- not always possible with a shunt. Among 130 consecutive carotid endarterectomies performed under general anesthesia, EEG changes consistent with cerebral ischemia appeared in only nine (7%). These patients required a shunt. In 11 patients normal EEG tracings were obtained during endarterectomy despite contralateral carotid occlusion. None of these patients had a neurological deficit. Continuous EEG monitoring is a reliable method of detecting changes in cerebral perfusion, permits a more meticulous endarterectomy in high-lying lesions without a shunt, and extends operability in high risk patients. Angiographical findings may be an unreliable predictor concerning risk of endarterectomy.  (+info)

Intensive care management of stroke patients. (7/10381)

Two hundred eighty patients were admitted to an intensive care stroke unit over a one-year period. Subsequent investigation indicated that only 199 of these patients actually had cerebral ischemic or hemorrhagic lesions, 10 had other cerebrovascular lesions, and the remaining 71 patients had unrelated diseases, predominantly seizures. Detailed analysis of 103 stroke patients revealed an overall incidence of 59% hypertension, and 72% had hypertensive, ischemic or valvular heart disease. Fifty percent of the patients had various cardiac arrhythmias, some of which were responsible for the acute cerebrovascular lesion. Fourteen patients died during the acute phase, 11 from apparently irreversible cerebral selling, mainly due to cerebral hemorrhage. Secondary complications such as pneumonia, pulmonary embolism, pressure sores and urinary infection were almost nonexistent, but beneficial effects on the primary cerebral lesions were more difficult to demonstrate.  (+info)

Subcortical arteriosclerotic encephalopathy (Binswanger's disease). A vascular etiology of dementia. (8/10381)

A 51-yearold man with moderate intermittent hypertension had a rapidly progressive, profound dementia in the absence of significant localizing neurological signs. Postmortem examination disclosed the vascular alterations and diffuse white matter degeneration which characterize subcortical arteriosclerotic encephalopathy (SAE) or Binswanger's disease. The case underscores the need to consider vascular disease as an etiology of dementia -- even in the absence of focal neurological deficit.  (+info)

Objective: We aimed to clarify the patterns of ictal power and phase lag among bilateral hemispheres on scalp electroencephalography (EEG) recorded pre-operatively during epileptic spasms (ESs) and the correlation with the outcomes following corpus callosotomy.Methods: We enrolled 17 patients who underwent corpus callosotomy for ESs before 20 years of age. After corpus callosotomy, seven patients did not experience further ESs (favorable outcome group), and the remaining 10 patients had ongoing ESs (unfavorable outcome group). We used pre-operative scalp EEG data from monopolar montages using the average reference. The relative power spectrum (PS), ictal power laterality (IPL) among the hemispheres, and phase lag, calculated by the cross-power spectrum (CPS) among symmetrical electrodes (i.e., F3 and F4), were analyzed in the EEG data of ESs from 143 pre-operative scalp video-EEG records.

electroencephalographs
Definition : Encephalographs designed for recording the variations of the electric potential caused by the electrical activity of the brain, usually detected on the scalp. These recorders consist of a main unit that includes memory (e.g., strip chart, flash card), signal processors, and a cable that is connected at the distal tip through a head box (amplifying unit) to a set of electrodes. The electrodes are typically placed on a cap or net fixed on the scalp in an array of standardized positions. Intracranial electrodes are used in very specific procedures. The electrodes and leads transmit the bioelectrical signals to a recorder which is capable of storing their characteristics for later display in an amplitude versus time graph (i.e., an electroencephalogram); some recorders can also provide a spectral analysis of the signals using a dedicated firmware. Electroencephalographs (EEGs) are used to help in the diagnosis of neurological diseases (e.g., epilepsy), to assist in localizing tumors and ...

AU - Slaets, J P. PY - 1996/4. Y1 - 1996/4. N2 - The sensitivity of the EEG in early AD is somewhat limited. In this respect spectral analysis is little better than visual assessment. In this study we address the question whether a new type of EEG analysis derived from chaos theory can improve the sensitivity of the EEG. EEGs were recorded in 15 control subjects and 15 patients with mild AD. The EEG recorded at 02 and 01 during eyes closed and eyes open conditions was subjected to spectral analysis (relative power) and nonlinear analysis (calculation of the correlation dimension D2). AD patients had more relative theta power and impaired reactivity in alpha, delta and theta bands. Also, reactivity of the D2 was impaired in AD subjects. For a specificity of 100%, relative theta power had the highest ...

To investigate using quantitative EEG the (1) differences between patients with mild cognitive impairment with Lewy bodies (MCI-LB) and MCI with Alzheimers disease (MCI-AD) and (2) its utility as a potential biomarker for early differential diagnosis. We analyzed eyes-closed, resting-state, high-density EEG data from highly phenotyped participants (39 MCI-LB, 36 MCI-AD, and 31 healthy controls). EEG measures included spectral power in different frequency bands (delta, theta, pre-alpha, alpha, and beta), theta/alpha ratio, dominant frequency, and dominant frequency variability. Receiver operating characteristic (ROC) analyses were performed to assess diagnostic accuracy. There was a shift in power from beta and alpha frequency bands towards slower frequencies in the pre-alpha and theta range in MCI-LB compared to healthy controls. Additionally, the dominant frequency was slower in MCI-LB compared to controls. We found significantly increased pre-alpha power, decreased beta power, and slower dominant

Spontaneous fluctuations of ongoing brain activity can be observed across a wide range of states, from sleep and even sedation, anesthesia, and coma over resting wakefulness all the way to effortful mental activity (Fox and Raichle, 2007). The fluctuations are spatially organized into ICNs. Their spatial patterns remain qualitatively robust across the different states but show fine-grained quantitative changes of connectivity (Horovitz et al., 2009; Vanhaudenhuyse et al., 2010). EEG has a longstanding tradition in monitoring and actually defining different brain states but it has also recently been shown to reflect activity fluctuations occurring within a given state as resting wakefulness. Activity in different ICNs, as recorded for instance in resting state fMRI studies, has been tied to power in different EEG frequency bands or even patterns of power across the EEG spectrum (Mantini et al., 2007). Here, we have pursued a hypothesis derived from previous work and focused on slow activity ...

Symmetrical event-related EEG/fMRI information fusion in a variational Bayesian framework. - Wellcome Centre for Integrative...
In this work, we propose a symmetrical multimodal EEG/fMRI information fusion approach dedicated to the identification of event-related bioelectric and hemodynamic responses. Unlike existing, asymmetrical EEG/fMRI data fusion algorithms, we build a joint EEG/fMRI generative model that explicitly accounts for local coupling/uncoupling of bioelectric and hemodynamic activities, which are supposed to share a common substrate. Under a dedicated assumption of spatio-temporal separability, the spatial profile of the common EEG/fMRI sources is introduced as an unknown hierarchical prior on both markers of cerebral activity. Thereby, a devoted Variational Bayesian (VB) learning scheme is derived to infer common EEG/fMRI sources from a joint EEG/fMRI dataset. This yields an estimate of the common spatial profile, which is built as a trade-off between information extracted from EEG and fMRI datasets. Furthermore, the spatial structure of the EEG/fMRI coupling/uncoupling is learned exclusively from the data. The

This is a test that uses a video camera linked to an EEG machine. The camera will visually record your movements and, at the same time, the EEG machine will record your brainwave pattern. Both the video and EEG are stored on to a computer so that they can be reviewed once the test is finished. The doctor will be able to see any seizures that you may have had, as well as any changes in your EEG at that time.

Differences in the neural systems underlying visual search processes for young (n=17, mean age 19.6+/-1.9) and older (n=22, mean age 68.5+/-6) subjects were investigated combining the Event-Related Potential (ERP) technique with standardized Low-Resolution brain Electromagnetic Tomography (sLORETA) analyses. Behavioral results showed an increase in mean reaction times (RTs) and a reduction in hit rates with age. The ERPs were significantly different between young and older subjects at the P3 component, showing longer latencies and lower amplitudes in older subjects. These ERP results suggest an age-related decline in the intensity and speed of visual processing during visual search that imply a reduction in attentional resources with normal aging. The sLORETA data revealed a significantly reduced neural differentiation in older subjects, who recruited bilateral prefrontal regions in a nonselective manner for the different search arrays. Finally, sLORETA between-group comparisons revealed that relative

Frontiers | Long-Range Temporal Correlations in Resting State Beta Oscillations are Reduced in Schizophrenia | PsychiatryFrontiers | Long-Range Temporal Correlations in Resting State Beta Oscillations are Reduced in Schizophrenia | Psychiatry
Symptoms of schizophrenia (SCZ) are likely to be generated by genetically mediated synaptic dysfunction, which contribute to large-scale functional neural dysconnectivity. Recent electrophysiological studies suggest that this dysconnectivity is present not only at a spatial level but also at a temporal level, operationalized as long-range temporal correlations (LRTCs). Previous research suggests that alpha and beta frequency bands have weaker temporal stability in people with SCZ. This study sought to replicate these findings with high-density electroencephalography (EEG), enabling a spatially more accurate analysis of LRTC differences, and to test associations with characteristic SCZ symptoms and cognitive deficits. A 128-channel EEG was used to record eyes-open resting state brain activity of 23 people with SCZ and 24 matched healthy controls (HCs). LRTCs were derived for alpha (8-12 Hz) and beta (13-25 Hz) frequency bands. As an exploratory analysis, LRTC was source projected using sLoreta. People

Coppola G, Ambrosini A, Di Clemente L, Magis D, Fumal A, Gérard P, Pierelli F & Schoenen J. Interictal abnormalities of gamma band activity in visual evoked responses in migraine: an indication of thalamocortical dysrhythmia? Cephalalgia 2007; 27:1360-1367. London. ISSN 0333-1024. Between attacks, migraineurs lack habituation in standard visual evoked potentials (VEPs). Visual stimuli also evoke high-frequency oscillations in the gamma band range (GBOs, 20-35 Hz) assumed to be generated both at subcortical (early GBOs) and cortical levels (late GBOs). The consecutive peaks of GBOs were analysed regarding amplitude and habituation in six successive blocks of 100 averaged pattern reversal (PR)-VEPs in healthy volunteers and interictally in migraine with (MA) or without aura patients. Amplitude of the two early GBO components in the first PR-VEP block was significantly increased in MA patients. There was a significant habituation deficit of the late GBO peaks in migraineurs. The increased ...

Granger Causality Analysis of Steady-State Electroencephalographic Signals during Propofol-Induced AnaesthesiaGranger Causality Analysis of Steady-State Electroencephalographic Signals during Propofol-Induced Anaesthesia
Changes in conscious level have been associated with changes in dynamical integration and segregation among distributed brain regions. Recent theoretical developments emphasize changes in directed functional (i.e., causal) connectivity as reflected in quantities such as integrated information and causal density. Here we develop and illustrate a rigorous methodology for assessing causal connectivity from electroencephalographic (EEG) signals using Granger causality (GC). Our method addresses the challenges of non-stationarity and bias by dividing data into short segments and applying permutation analysis. We apply the method to EEG data obtained from subjects undergoing propofol-induced anaesthesia, with signals source-localized to the anterior and posterior cingulate cortices. We found significant increases in bidirectional GC in most subjects during loss-of-consciousness, especially in the beta and gamma frequency ranges. Corroborating a previous analysis we also found increases in synchrony in

Anatomical functionality is a major topic in brain research. Numerous investigations have shown task dependent activation of focal brain areas, with most information based on time-averaged data due to methodological limitations. Ultra-fast quantitative EEG, especially in the newly developed combination with eye tracking (EnkephaloVision), is very suitable to follow activities of local electric circuits. This investigation in 57 subjects revealed transient focal frequency changes reaching up to more than 6000% of global median spectra power during cognitive and emotional challenges at frontal electrode positions. Recording epochs of 364 ms uncovered coherences with respect to focal brain areas and single frequencies, which are typically lost during averaged calculations. When averaging data over a whole scene, a least demanding challenge like viewing a boring animal video only activated the lateral frontal lobe, whereas solving brain-teasers and performance of mathematical calculations led to delta

Objective The significant impact of stroke on health care results in an unmet need for efficient stroke care in resources limited environments. Practical, inexpensive and easy to obtain predictive EEG parameters have been suggested in anterior circulation syndromes. We investigated whether EEG parameters are of additional predictive value with regard to lesion volume and short-term functional outcome in lacunar (LACS) and posterior circulation (POCS) syndromes of presumed ischemic origin. Methods Sixty (60) patients presenting with LACS or POCS were incrementally included. EEG parameters were correlated with volume of ischemia and functional status. Predictive values for definite stroke and unfavourable outcome were calculated using receiver operating characteristic (ROC) curves and logistic regression modelling. Results The pairwise derived brain symmetry index (pdBSI) emerged as independent predictor for definite stroke in patients presenting with LACS and POCS (odds ratio (OR) 2.69, 95% ...

Your Brain Waves May Show Whether Youre Paying Attention in Class
You really can get on the same wavelength as someone else: In a new study, the brain waves of high school students synced up when they were highly engaged during a biology class.. On 11 days over the course of one semester, researchers hooked up all 12 of the students in a biology class to portable devices called electroencephalograms (EEGs) that measured their brain waves. The more synced up a students brain waves were with the brain waves of the rest of the students in the class, the more likely that person was to say that he or she enjoyed the class that day, according to the study, published today (April 27) in the journal Current Biology. For example, when the researchers analyzed brain waves called alpha waves, they found that students waves were more likely to rise and fall at the same time as other students waves when they were highly engaged in the class.. Likewise, when a students brain waves were less synced with those of the rest of the class, the student was less likely to say ...

Neurophysiological Mechanisms - Oxford ScholarshipNeurophysiological Mechanisms - Oxford Scholarship
The seventh part of this book deals with possible neurophysiological mechanisms involved in motor synergies. It starts with a discussion of the structure-function controversy in neurophysiology. Then, it presents reviews of the literature on the role in synergy formation of different structures within the central nervous system such as the spinal cord, the cerebellum, the basal ganglia, and the cortex of the large hemispheres. The review covers animal studies, studies of patients with different neurological disorders, and studies of healthy persons. Studies using transcranial magnetic stimulation are reviewed with respect to the equilibrium-point hypothesis of movement control. Relations between neuronal population vectors and performance variables are discussed. There is one more Digression in this part addressing the issue of localization of functions within brain structures.

Computer analysis of epileptiform EEG abnormalities | Cleveland Clinic Journal of MedicineComputer analysis of epileptiform EEG abnormalities | Cleveland Clinic Journal of Medicine
AbstractPROLONGED multichannel electroencephalographic (EEG) recordings are required for the evaluation of an epilepsy surgery candidate in order to define precisely the epileptogenic areas, the patients suitability for surgical treatment, and the extent of a proposed resection. An adequate sample of ictal and interictal EEG abnormalities must be obtained to make these important clinical decisions. The minimal monitoring period required to obtain the sample varies from patient to patient, but should be as short as possible.Minimizing the time away from home is especially important when recording from pediatric patients. Children do not understand the importance of the diagnostic test, may be less patient in a restricted and boring setting, and are more likely to interfere with the apparatus. Nevertheless, a positive diagnosis and definite classification are more important at this stage of life than at any other. In patients of any age requiring intensive inpatient EEG monitoring, a computer system can

Normal frequencies of the human brain associated states are shown below. These frequencies can be picked up by an EEG (Electroencephalogram) from the surface of the brain, after their amplification, as they are in the range of micro-volts. A mixture of these frequencies is present at any given time. Quantitative Electroencephalography (QEEG) is an extension of the analysis of the visual EEG interpretation which may assist and even augment our understanding of the EEG and brain function.

UBIRA ETheses - Neurophysiological correlates of preparation for action measured by electroencephalographyUBIRA ETheses - Neurophysiological correlates of preparation for action measured by electroencephalography
The optimal performance of an action depends to a great extend on the ability of a person to prepare in advance the appropriate kinetic and kinematic parameters at a specific point in time in order to meet the demands of a given situation and to foresee its consequences to the surrounding environment. In the research presented in this thesis, I employed high-density electroencephalography in order to study the neural processes underlying preparation for action. A typical way for studying preparation for action in neuroscience is to divide it in temporal preparation (when to respond) and event preparation (what response to make). In Chapter 2, we identified electrophysiological signs of implicit temporal preparation in a task where such preparation was not essential for the performance of the task. Electrophysiological traces of implicit timing were found in lateral premotor, parietal as well as occipital cortices. In Chapter 3, explicit temporal preparation was assessed by comparing anticipatory ...

IJERPH | Free Full-Text | Binge Drinking Effects on EEG in Young Adult Humans | NotesIJERPH | Free Full-Text | Binge Drinking Effects on EEG in Young Adult Humans | Notes
Young adult (N = 96) university students who varied in their binge drinking history were assessed by electroencephalography (EEG) recording during passive viewing. Groups consisted of male and female non-binge drinkers (|1 to 5/4 drinks/ounces in under two hours), low-binge drinkers (5/4-7/6 drinks/ounces in under two hours), and high-binge drinkers (≥ 10 drinks/ounces in under two hours), who had been drinking alcohol at their respective levels for an average of 3 years. The non- and low-binge drinkers exhibited less spectral power than the high-binge drinkers in the delta (0-4 Hz) and fast-beta (20-35 Hz) bands. Binge drinking appears to be associated with a specific pattern of brain electrical activity in young adults that may reflect the future development of alcoholism.

1)From neurophysiology to neuroimaging: In neurophysiology, neural oscillation is usually well recorded as local field potentials (LFPs). It represents the summation of postsynaptic potentials occurring in the cortical layers. From clinical point of view, clinical EEG in the 20th century used to record rather limited range of frequency activity from delta to gamma activity but did not exceed down to < 1Hz or up to > 100Hz. With much higher sampling rate of > 1K or 2K Hz in the digital EEG equipment, high frequency activity such as ripple or fast ripple activity are well recorded not only by microelectrodes (Le Van Quyen et al, 2008) but also by macroelectrode such as subdural or depth electrode in humans. It could represent the synchronous action potential firing of a group of principal cells (Jefferys et al, 2012). By opening low frequency filter of AC amplifier down to 10 sec, it could also record very slow shifts or baseline shifts. By means of functional MRI (fMRI) in human brain function, ...

Author(s): Rabinoff, M; Kitchen, CMR; Cook, IA; Leuchter, AF | Abstract: The study objective was to evaluate the usefulness of Classification and Regression Trees (CART), to classify clinical responders to antidepressant and placebo treatment, utilizing symptom severity and quantitative EEG (QEEG) data. Patients included 51 adults with unipolar depression who completed treatment trials using either fluoxetine, venlafaxine or placebo. Hamilton Depression Rating Scale (HAM-D) and single electrodes data were recorded at baseline, 2, 7, 14, 28 and 56 days. Patients were classified as medication and placebo responders or non-responders. CART analysis of HAM-D scores showed that patients with HAM-D scores lower than 13 by day 7 were more likely to be treatment responders to fluoxetine or venlafaxine compared to non-responders (p=0.001). Youdens index γ revealed that CART models using QEEG measures were more accurate than HAM-D-based models. For patients given fluoxetine, patients with a decrease at day 2 in

Detection of synchronized oscillations in the electroencephalogram: an evaluation of methods. - Nuffield Department of Clinical...
The signal averaging approach typically used in ERP research assumes that peaks in ERP waveforms reflect neural activity that is uncorrelated with activity in the ongoing EEG. However, this assumption has been challenged by research suggesting that ERP peaks reflect event-related synchronization of ongoing EEG oscillations. In this study, we investigated the validity of a set of methods that have been used to demonstrate that particular ERP peaks result from synchronized EEG oscillations. We simulated epochs of EEG data by superimposing phasic peaks on noise characterized by the power spectrum of the EEG. When applied to the simulated data, the methods in question produced results that have previously been interpreted as evidence of synchronized oscillations, even though no such synchrony was present. These findings suggest that proposed analysis methods may not effectively disambiguate competing views of ERP generation.

MRI with and without a high-density EEG cap--what makes the difference? - Zurich Open Repository and ArchiveMRI with and without a high-density EEG cap--what makes the difference? - Zurich Open Repository and Archive
Besides the benefit of combining electroencephalography (EEG) and magnetic resonance imaging (MRI), much effort has been spent to develop algorithms aimed at successfully cleaning the EEG data from MRI-related gradient and ballistocardiological artifacts. However, there are also studies showing a negative influence of the EEG on MRI data quality. Therefore, in the present study, we focused for the first time on the influence of the EEG on morphometric measurements of T1-weighted MRI data (voxel- and surfaced-based morphometry). Here, we demonstrate a strong influence of the EEG on cortical thickness, surface area, and volume as well as subcortical volumes due to local EEG-related inhomogeneities of the static magnetic (B0) and the gradient field (B1). In a second step, we analyzed the signal-to-noise ratios for both the anatomical and the functional data when recorded simultaneously with EEG and MRI and compared them to the ratios of the MRI data without simultaneous EEG measurements. These ...

In this work we consider hidden signs (biomarkers) in ongoing EEG activity expressing epileptic tendency, for otherwise normal brain operation. More specifically, this study considers children with controlled epilepsy where only a few seizures without complications were noted before starting medication and who showed no clinical or electrophysiological signs of brain dysfunction. We compare EEG recordings from controlled epileptic children with age-matched control children under two different operations, an eyes closed rest condition and a mathematical task. The aim of this study is to develop reliable techniques for the extraction of biomarkers from EEG that indicate the presence of minor neurophysiological signs in cases where no clinical or significant EEG abnormalities are observed. We compare two different approaches for localizing activity differences and retrieving relevant information for classifying the two groups. The first approach focuses on power spectrum analysis whereas the second

Brain waves, or the EEG, are electrical signals that can be recorded from the brain, either directly or through the scalp. The kind of brain wave recorded depends on the behavior of the animal, and is the visible evidence of the kind of neuronal (brain cell) processing necessary for that behavior.. We are working on fast brain waves, at about 40 cycles per second (Hz), which are known as gamma band. Gamma rhythms appear to be involved in higher mental activity, including perception and consciousness. It seems to be associated with consciousness, eg it disappears with general anesthesia.. Synchronous activity at about 40Hz appears to be involved in binding sensory inputs into the single, unitary object we perceive. This process is so efficient, we are hardly aware that it goes on at all. Recordings of neurons in visual cortex show that synchronization at about 40 Hz links parts of the cortex excited by the same object, and not those excited by different objects, implicating in gamma rhythms in ...

AU - Maguire, LP. PY - 2011. Y1 - 2011. N2 - This paper describes an investigation into the pathophysiological causes of abnormal cortical oscillations in Alzheimers disease (AD) using two heterogeneous neuronal network models. The effect of excitatory circuit disruption on the beta band power (13-30 Hz) using a conductance-based network model of 200 neurons is assessed. Then, the neural correlates of abnormal cortical oscillations in different frequency bands based on a larger network model of 1000 neurons consisting of different types of cortical neurons is also analyzed. The results show that, despite the heterogeneity of the network models, the beta band power is significantly affected by excitatory neural and synaptic loss. Secondly, the results of modeling a functional impairment in the excitatory circuit ...

A number of recent studies have hypothesized that monitoring in speech production may occur via domain-general mechanisms responsible for the detection of response conflict. Outside of language, two ERP components have consistently been elicited in conflict-inducing tasks (e.g., the flanker task): the stimulus-locked N2 on correct trials, and the response-locked error-related negativity (ERN). The present investigation used these electrophysiological markers to test whether a common response conflict monitor is responsible for monitoring in speech and non-speech tasks. Electroencephalography (EEG) was recorded while participants performed a tongue twister (TT) task and a manual version of the flanker task. In the TT task, people rapidly read sequences of four nonwords arranged in TT and non-TT patterns three times. In the flanker task, people responded with a left/right button press to a center-facing arrow, and conflict was manipulated by the congruency of the flanking arrows. Behavioral ...

A Quantitative Electroencephalography Study on Cochlear Implant-Induced Cortical Changes in Single-Sided Deafness with TinnitusA Quantitative Electroencephalography Study on Cochlear Implant-Induced Cortical Changes in Single-Sided Deafness with Tinnitus
The mechanism of tinnitus suppression after cochlear implantation (CI) in single-sided deafness (SSD) is not fully understood. In this regard, by comparing pre-and post-CI quantitative electroencephalography (qEEG), we explored cortical changes relevant to tinnitus improvement. In SSD patients who underwent CI, qEEG data were collected: (1) before CI, (2) 6 months post-operatively with CI-on, and (3) 30 min after CI-off and source-localized cortical activity/functional connectivity analyses were performed. Compared to the pre-operative baseline, the CI-on condition demonstrated significantly decreased activity in the right auditory-and orbitofrontal cortices (OFC) for the delta frequency band as well as decreased connectivity between the auditory cortex/posterior cingulate cortex for the delta/beta2 bands. Meanwhile, compared to the CI-off condition, the CI-on condition displayed decreased activity in the right auditory cortices/OFC for the delta band, and in bilateral auditory cortices, left ...

AU - Demaree, Heath A.. AU - Delgado, Pedro L.. PY - 2009/5/1. Y1 - 2009/5/1. N2 - Background: Tryptophan depletion (TD) reduces brain serotonin and may induce acute depressive symptomatology, especially among those with a history of Major Depression. Depressive response to TD among euthymic patients with a history of depression also predicts future depression. Better prediction might result by assessing a putative endophenotype for depressive risk, frontal electroencephalographic (EEG) asymmetry, in the context of TD. Method: Nine euthymic history-positive participants and nine controls were administered TD. Symptomatic and EEG frontal asymmetry data were collected for 6 h following TD, and clinical status was followed for the next 12 months. Results: The magnitude of TD-induced change in frontal EEG asymmetry ...

[more ▼]. Electroencephalographic activity in the context of disorders of consciousness is a swiss knife like tool that can evaluate different aspects of cognitive residual function, detect consciousness and provide a mean to communicate with the outside world without using muscular channels. Standard recordings in the neurological department offer a first global view of the electrogenesis of a patient and can spot abnormal epileptiform activity and therefore guide treatment. Although visual patterns have a prognosis value, they are not sufficient to provide a diagnosis between vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious state (MCS) patients. Quantitative electroencephalography (qEEG) processes ...

L-theanine, Health Benefits and Cognitive Function - Blog - iHerbL-theanine, Health Benefits and Cognitive Function - Blog - iHerb
The anti-anxiety effects of L-theanine are mediated through different mechanisms including enhanced alpha brain wave activity, increased synthesis of GABA, and its role as a weak antagonist of AMPA glutamate receptors. General calming benefits of l-theanine are reflected in increased brain electrical activity in the alpha frequency range (8 to 13 Hz). Changes in brain electrical activity measured by electroencephalography (EEG) are dose-dependent, and are similar to beneficial EEG changes observed in meditation, including increased alpha waves in the occipital and parietal regions. Increased alpha activity has been shown to continue for 60 minutes following administration of a 200mg dose of l-theanine, and this effect was more marked in individuals with higher trait anxiety. Finally, ingestion of green tea with high l-theanine content has been found to decrease adrenal hypertrophy in mice exposed to chronic stress. Individuals who drink green tea for stress or anxiety may experience greater ...

Event-related potentials in electroencephalography characteristics and by Yonghong HuangEvent-related potentials in electroencephalography characteristics and by Yonghong Huang
Brain computer interfaces (BCIs) provide a non-muscular avenue for the user to communicatewith others and to control external devices. Over the last two decades BCIs have been developed to assist the severely motor-disabled people, such as traumatic braininjury, stroke, or amyotrophic lateral sclerosis. Electroencephalography (EEG) is one of the most popular noninvasive BCI approaches. The inputs to EEG-based BCIs are event-related potentials (ERPs), which are neural signatures representing the responses to an external stimulus. Traditional BCI systems, which have had some success, make inferences based on trial-averaged ERPs, where each trial consists of one stimulus. In this thesis, (1) we develop a single-trial, EEG-based BCI to increase the throughput of visual image search and (2) we unveil a neural correlate of human visual perception that occurs in rapid visual-recognition tasks. Our first task is to develop a BCI. Our BCI makes inferences from single-trial ERPs; hence, it is more efficient than

All experiments were conducted between 9 and 19 h. The experimental design of this study is illustrated in figure 1A. On the day of the experiment, anesthesia was initially induced in a chamber using 4-5% isoflurane (vaporizer setting) in 100% oxygen (2 l/min). After loss of the righting reflex (LORR) and evaluation of changes in respiratory rate, the animals were exposed to 1, 1.4, or 2.1% isoflurane (with 100% oxygen, flow rate 1 l/min) via a facemask connected to a scavenging system. The isoflurane vaporizer was used throughout the study, and stability of output over time was verified by an infrared gas analyzer. The 1%, 1.4%, and 2.1% isoflurane were considered to be the minimum alveolar concentration values of 0.7, 1.0, and 1.5, respectively, in rats.22 Body temperature was determined rectally and maintained at 37.0-37.5°C with a heating lamp. In Experiment 1, a 30-gauge injection cannula was introduced through the guide cannula into the NBM after a 30-min equilibration period with 1.4% ...

The physiopathological mechanism underlying the tinnitus phenomenon is still the subject of an ongoing debate. Since oscillatory EEG activity is increasingly recognized as a fundamental hallmark of cortical integrative functions, this study investigates deviations from the norm of different resting EEG parameters in patients suffering from chronic tinnitus. Spectral parameters of resting EEG of male tinnitus patients (n = 8, mean age 54 years) were compared to those of age-matched healthy males (n = 15, mean age 58.8 years). On average, the patient group exhibited higher spectral power over the frequency range of 2-100 Hz. Using LORETA source analysis, the generators of delta, theta, alpha and beta power increases were localized dominantly to left auditory (Brodmann Areas (BA) 41,42, 22), temporo-parietal, insular posterior, cingulate anterior and parahippocampal cortical areas. Tinnitus patients show a deviation from the norm of different resting EEG parameters, characterized by an overproduction of

Autoregressive Modeling Based Empirical Mode Decomposition (EMD) for Epileptic Seizures Detection Using EEG Signals | IIETA
Epilepsy is a neurological disorder affecting almost 1 % of humans on earth [1, 2]. This disease is characterized by repetitive seizures, shown by loss of muscle control, mental or conscious deficiency etc. Epileptic seizures are generally caused by brusque and ephemeral electrical discharges of synchronous association of brain cells [3]. Electroencephalography (EEG) defined as the recording of electrical brain activities by means of a set of electrodes directly placed on the scalp, can easily exhibit these electrical discharges. Hence it becomes evident that neurologists and other practioners would rely on the EEG recordings to explore possible epileptic seizures [3-7]. However, visual scanning of EEG records is a subjective process and would result in many different misinterpretations; it is considered as time consuming as records could persist for hours or even several days. Thus, computational methods would be necessary to realize automatic detection and classification of epileptic patterns ...

Electroclinical Features of Generalized Paroxysmal Fast Activity in Ty by Lalit R. Bansal, Lines Vargas Collado et al.Electroclinical Features of Generalized Paroxysmal Fast Activity in Ty by Lalit R. Bansal, Lines Vargas Collado et al.
PURPOSE: Generalized paroxysmal fast activity (GPFA) is a diffuse, paroxysmal, frontal predominant activity described in patients with generalized epilepsies. Studies specifically focusing on electroclinical features of typical absence seizures in children have not reported any GPFA-like features. We sought to identify GPFA in children with typical absence seizures, study its incidence, characteristic electroclinical features, and effect on their epilepsy. METHODS: We performed a retrospective review of electroencephalograms of children with diagnosis of absence epilepsy. A total of 173 subjects were identified. In subjects with GPFA on their electroencephalograms, GPFA characteristics were collected (i.e., predominant location, duration, amplitude, frequency, provocation factors, and if GPFA was followed by spike-wave discharges). In GPFA-positive subjects, further data sets were collected examining their demographics, duration of epilepsy, and pharmacoresponsiveness to epilepsy. RESULTS: Generalized

CDKL5 mutations in boys with severe encephalopathy and early-onset intractable epilepsy | NeurologyCDKL5 mutations in boys with severe encephalopathy and early-onset intractable epilepsy | Neurology
Elia et al. described the clinical and electroencephalographic features of three boys with CDKL5 mutations. [1] They concluded that, similarly to girls with this mutation, epilepsy appears to be polymorphous, with myoclonic, tonic, and partial seizures or spasms and that interictal EEG pattern is characterized by focal, multifocal, diffuse pseudoperiodic epileptiform activity. Elia considered these clinical and electroencephalographic observations similar to other findings. [2-3] However, the EEG pattern reported by Elia et al. was actually first described by us. [4] We described the seizures of three CDKL5 patients as starting as complex partial seizures or tonic spasms and then becoming complex partial, tonic, and unexpectedly, myoclonic seizures of such prominence to justify the definition of myoclonic encephalopathy. In this stage, the EEG showed an intercritical pattern with pseudoperiodic, diffuse sharp waves or pseudoperiodic, diffuse spike and polyspike and wave discharges and ...

Effects of organization and disorganization on pleasantness, calmness, and the frontal negativity in the event-related potentialEffects of organization and disorganization on pleasantness, calmness, and the frontal negativity in the event-related potential
A preference for organization is associated with several disorders, but is widespread in the general population as well. It remains unclear whether organization and various degrees of disorganization elicit pleasant or unpleasant feelings (i.e., valence), calming or arousing feelings (i.e., arousal), and a frontal negativity in the event-related potential (ERP) related to cognitive control. This study tested how organization, slight disorganization, and total disorganization affect valence, arousal, and the frontal negativity. Participants passively viewed organized, slightly disorganized, totally disorganized, and control pictures while their electroencephalogram was recorded. They also rated the valence and arousal elicited by each picture and completed questionnaires assessing desire for order and organization behavior. Organized pictures made participants feel most pleasant, control pictures made participants feel less pleasant, slightly disorganized pictures made participants feel even less

We examined a group of 77 autistic children (61 boys, 16 girls) of an average age 9.1 ± 5.3 years. The Childhood Autism Rating Scale (CARS), IQ test and 21 channel EEG (including night sleep EEG recording) were applied. It was possible to obtain evaluable EEG records in 63 patients. Missing EEG records were mostly due to noncooperation on the part of the autistic children. There were 28 normal EEGs (44.4%), 11 non-epileptiform abnormal EEGs (17.5%), and 24 abnormal EEGs with epileptiform discharges (38.1%). Using the median test, we compared the psychopathology in these three groups. No significant difference in the total CARS score was found among the groups. In the analysis of CARS items, there was only one significant difference among the groups in the 10th item - Fear or Nervousness (chi2 = 7.963, df = 2, p = 0.019 ...

Changing Electrode Montages After Recording (remontaging).. Veterinary EEG recording typically is performed under certain limitations. Because of the cost of equipment, most veterinary laboratories have had polygraphs with only 6 or 8 EEG channels. By comparison, thirty-two channels are now used in routine recordings from human patients and even more in some specialized studies. In addition to monetary limits, there is an inherent limit on the number of electrodes that can be placed on the head of most veterinary patients, whose calvaria are often smaller even than those of children..

Integrating cross-frequency and within band functional networks in resting-state MEG: A multi-layer network approach. -...
Neuronal oscillations exist across a broad frequency spectrum, and are thought to provide a mechanism of interaction between spatially separated brain regions. Since ongoing mental activity necessitates the simultaneous formation of multiple networks, it seems likely that the brain employs interactions within multiple frequency bands, as well as cross-frequency coupling, to support such networks. Here, we propose a multi-layer network framework that elucidates this pan-spectral picture of network interactions. Our network consists of multiple layers (frequency-band specific networks) that influence each other via inter-layer (cross-frequency) coupling. Applying this model to MEG resting-state data and using envelope correlations as connectivity metric, we demonstrate strong dependency between within layer structure and inter-layer coupling, indicating that networks obtained in different frequency bands do not act as independent entities. More specifically, our results suggest that frequency band

Benign Childhood Epilepsy with Centrotemporal Spikes: To Treat or Not to Treat
Table 3 presents results on the clinical and neuropsychological assessment of the subjects over time. 54% of OXC treatment group remained seizure free and 23% showed an average monthly reduction in seizure frequency of more than 50% during the first 6 month as did 50% and 19% of the non-treatment group. Statistically there was no significant difference between the two groups. The sleep EEGs became normalized in 15% of the treatment group and 19% of the non-treatment group after six months of treatment. As for the spike index, it increased by 20-50% in the treatment group after 6 months of treatment and fell by 20-90% in the non-treatment group over the same time period (p,0.05). Furthermore, the spike index of the right hemisphere decreased more in the non-treatment group than in the treatment group; however this different was not statistically significant (7.2±16.2 to 3.8±7.9 in NT vs. 15.5±17.6 to 19.1± 18.4 in T).

Electroencephalography (EEG) records fast-changing neuronal signalling and communication and thus can offer a deep understanding of cognitive processes. However, traditional data analyses which employ the Fast-Fourier Transform (FFT) have been of limited use as they do not allow time- and frequency-resolved tracking of brain activity and detection of directional connectivity. Here, we applied advanced qEEG tools using autoregressive (AR) modelling, alongside traditional approaches, to murine data sets from common research scenarios: (a) the effect of age on resting EEG; (b) drug actions on non-rapid eye movement (NREM) sleep EEG (pharmaco-EEG); and (c) dynamic EEG profiles during correct vs incorrect spontaneous alternation responses in the Y-maze ...

Continuous EEG Monitoring for Early Detection of Delayed Cerebral Ischemia in Subarachnoid Hemorrhage: A Pilot StudyContinuous EEG Monitoring for Early Detection of Delayed Cerebral Ischemia in Subarachnoid Hemorrhage: A Pilot Study
INTRODUCTION: Early identification of delayed cerebral ischemia (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH) is a major challenge. The aim of this study was to investigate whether quantitative EEG (qEEG) features can detect DCI prior to clinical or radiographic findings. METHODS: A prospective cohort study was performed in aSAH patients in whom continuous EEG (cEEG) was recorded. We studied 12 qEEG features. We compared the time point at which qEEG changed with the time point that clinical deterioration occurred or new ischemia was noted on CT scan. Results : Twenty aSAH patients were included of whom 11 developed DCI. The alpha/delta ratio (ADR) was the most promising feature that showed a significant difference in change over time in the DCI group (median -62 % with IQR -87 to -39 %) compared to the control group (median +27 % with IQR -32 to +104 %, p = 0.013). Based on the ROC curve, a threshold was chosen for a combined measure of ADR and alpha variability (AUC: 91.7, 95 ...

Diagnosing EpilepsyDiagnosing Epilepsy
Diagnosing Epilepsy. How is epilepsy diagnosed? There is no diagnostic test for a seizure or for epilepsy. The doctors diagnosis is based on a thorough investigation of a first seizure (including any witness observations), a physical examination, family history, and supportive tests such as the EEG, CT Scan, and MRI.. The description of what happens during during the seizure, along with any changes that happen before or after the seizure, are important features used by a healthcare providor to determine the seizure category and the seizure type. The duration of the seizure is another important feature.. What is an EEG?. The electroencephalograph or EEG directly measures electrical activity in the brain-brain waves-through the skin. In this harmless test, small sensors called electrodes are attached to the patients scalp. The electrical activity picked up by each sensor is graphed onto an EEG printout.. Tests are done on people with epilepsy commonly show uneven activity or large changes in the ...

A.E.Brain: How Close Is a Workable Brain-Computer Interface?A.E.Brain: How Close Is a Workable Brain-Computer Interface?
This paper describes a technique based on electroencephalography (EEG) to control a robot arm. This technology could eventually allow people with severe disabilities to control robots that can help them in daily living activities. The EEG-based Brain Computer Interface (BCI) developed consists in register the brain rhythmic activity through a electrodes situated on the scalp in order to differentiate one cognitive process from rest state and use it to control one degree of freedom of the robot arm. In the paper the processing and classifier algorithm are described and an analysis of their parameters has been made with the objective of find the optimum configuration that allow obtaining the best results ...

Age-related changes in orienting attention in time. - Department of Psychiatry
Temporal cues guide attentional resources toward relevant points in time, resulting in optimized behavioral performance. Although deficits in aspects of attention have been documented in older adults, it remains unknown whether the critical ability to orient attention in time is affected by normal aging. To address this, younger and older adults participated in a temporally cued target-response experiment while electroencephalographic data were recorded. Three conditions (one detection and two discrimination tasks) were used to manipulate task complexity. Response times show that younger adults, but not older adults, used temporal cues to enhance performance regardless of task complexity. Similarly, alpha band activity (8-12 Hz) and the contingent negative variation preceding targets indicated that only younger adults engaged prestimulus, anticipatory neural mechanisms associated with temporal cues. Overall, these results provide novel evidence that older adults do not use temporal cues to orient

Heart beats brain: the problem of detecting alpha waves by neuronal current imaging in joint EEG-MRI experiments - Zurich Open...Heart beats brain: the problem of detecting alpha waves by neuronal current imaging in joint EEG-MRI experiments - Zurich Open...
It has been suggested recently that the influence of the neuro-magnetic field should make electrical brain activity directly detectable by MRI. To test this hypothesis, we performed combined EEG-MRI experiments which aim to localize the neuronal current sources of alpha waves (8-12 Hz), one of the most prominent EEG phenomena in humans. A detailed analysis of cross-spectral coherence between simultaneously recorded EEG and MRI time series revealed no sign of alpha waves. Instead the EEG-MRI approach was found to be hampered by artefacts due to cardiac pulsation, which extend into the frequency band of alpha waves. Separate brain displacement mapping experiments confirmed that not only the EEG but also the MRI signal is confounded by harmonics of the cardiac frequency even at 10 Hz and beyond. This well-known ballistocardiogram artefact cannot be avoided or eliminated entirely by available signal processing techniques. Therefore we must conclude that current EEG-MRI methodology based on ...

Electroencephalography and subjective ratings of sleep deprivationElectroencephalography and subjective ratings of sleep deprivation
Sleep-related vehicle accidents account for many injuries and fatalities each year on monotonous motorways and roads. To effectively prevent such incidents requires greater knowledge of the mechanisms and development of the effects of sleep deprivation. Ten volunteers participated in a laboratory study aimed to analyze the way changes in wakefulness were described in terms of EEG changes and subjective ratings. Patients and methods For each subject, the study consisted of four testing sessions that varied in length on different days: one session each of 60, 90, and 120 min when sleep-deprived, and one session of 120 min when rested. Changes in wakefulness were analyzed using electroencephalographic recordings and ratings on two different scales, the Karolinska Sleepiness Scale (KSS) and the Category-Ratio Scale (CR-10). Results The results indicate quite conclusively that significant changes in the perception of sleepiness occur during the first 60-90 min of sedentary, monotonous work. Beyond ...
