Understanding the generation of beta oscillations is important to improve treatments for Parkinsons disease. Competing theories exist for how these oscillations are generated in the affected brain circuits, which include the motor cortex and a set of subcortical nuclei called the basal ganglia. This paper suggests two hypotheses for the generation of beta oscillations. The first hypothesis is that beta oscillations are generated in the motor cortex, and the basal ganglia resonate to the cortical input. The second hypothesis additionally proposes that feedback from the basal ganglia to cortex is critically important for the presence of the oscillations. We show that the models can successfully account for a wide range of experimental data concerning the presence of beta oscillations in Parkinsons disease ...

Hypokinetic symptoms of Parkinsons disease are usually associated with the excessively strong oscillations and synchrony in the beta frequency band. The origin of this synchronized oscillatory dynamics is being debated. Cortical circuits may be a critical source of excessive beta in Parkinsons disease. However, subthalamo-pallidal circuits were also suggested to be a substantial component in generation and/or maintenance of Parkinsonian beta activity. Here we study how the subthalamo-pallidal circuits interact with input signals in the beta frequency band, representing cortical input. We use conductance-based models of the subthalamo-pallidal network and two types of input signals: artificially-generated inputs and input signals obtained from recordings in Parkinsonian patients. The resulting model network dynamics is compared with the dynamics of the experimental recordings from patients basal ganglia. Our results indicate that the subthalamo-pallidal model network exhibits multiple ...

Pain studies using electrophysiological recording (EEG, Evoked Potentials (EP) and MEG) demonstrate shifts in the frequency spectrum in the presence of chronic or induced pain, to the theta and beta frequency bands. Source localization of scalp-recorded EEG data Low-Resolution Electromagnetic Tomographic Analysis (LORETA) in patients with intractable unilateral or bilateral neuropathic pain, when compared to pain-free controls identified similar neural activity sources as reported in the literature with conventional neuroimaging methods.. Preliminary data collected at the Brain Research Laboratories, Department of Psychiatry at NYUSOM (under a research contract from PainQx) has been published demonstrating feasibility/proof of concept for an approach which uses QEEG to identify and quantify significant over and under activation of cortical and subcortical regions of interest (ROI) of the brain in a chronic pain population. Using QEEG source localization methods, this published pilot study ...

In cooperation with her working group, Prof. Dr. Ilka Diester of the University of Freiburgs Institute of Biology III and excellence cluster BrainLinks-BrainTools has developed a new method for analyzing data in the brain. They are using their method to detect short beta wave bursts in real time within neural frequency bands of around 20 Hertz and to show how rats can increase the occurrence of these bursts. The researchers have published their results in the scientific journal „Nature Communication Biology.. In humans, monkeys, and rodents, it is possible to detect short bursts of up to 150 milliseconds of beta waves - a specific section of the brainwave spectrum - within a frequency range of 15 hertz to 30 hertz. Researchers up to now connected these events with memory, motion, and perception. During what is known as neuro-feedback training, rats always receive a reward when their brain produces a burst in the beta frequency range. This increases not only the recurrence of beta frequency ...

The voluntary step execution task is a popular measure for identifying fall risks among elderly individuals in the community setting because most falls have been reported to occur during movement. However, the neurophysiological functions during this movement are not entirely understood. Here, we used electromyography (EMG) to explore the relationship between EMG-EMG coherence, which reflects common oscillatory drive to motoneurons, and motor performance associated with stepping tasks: simple reaction time (SRT) and choice reaction time (CRT) tasks. Ten healthy elderly adults participated in the study. Participants took a single step forward in response to a visual imperative stimulus. EMG-EMG coherence was analyzed for 1,000 ms before the presentation of the stimulus (stationary standing position) from proximal and distal tibialis anterior (TA) and soleus (SOL) muscles. The main result showed that all paired EMG-EMG coherences in the alpha and beta frequency bands were greater in the SRT than the CRT

disruption phenotype: The birth rate of knockout mice on a C57BL/6 background is very low (approximately 10% of pups). The animals appear normal, but their growth after birth is severely retarded. Half of them die by the end of the weaning period. Mutant mice have profoundly impaired T-helper type 1 lymphocyte (Th1)-mediated responses (PubMed:17998391). On a BALB/c background, under resting conditions, they show spastic or dystonic features and, during the open field test, they exhibit hyperactivity and anxiety. Their resting electroencephalography show enhanced activity in the fast beta frequency band (20-35 Hz). They do not show any apparent structural brain anomaly (PubMed:29394991 ...

Comparison of the EEGs of 27 healthy older adults, 27 individuals with mild Alzheimers and 22 individuals with moderate cases of Alzheimers, has found statistically significant differences across the three groups, using an algorithm that dissects brain waves of varying frequencies.. In particular, delta modulation of the beta frequency band reliably discriminated between healthy controls and mild Alzheimers, and disappeared with an increase in disease severity (from mild to moderate). Increase in disease severity was also marked by the appearance of delta modulation of the theta band.. Its hoped that the algorithm can be used not only to help detect Alzheimers disease early, but also to monitor its progression. The algorithm has been shared on the NeuroAccelerator.org online data analysis portal, to enable it to be used by researchers around the world.. http://www.eurekalert.org/pub_releases/2013-08/i-tae082913.php.

The test subjects participated in various neuropsychological and EEG tests. For example, spontaneous activity was measured in a relaxed state when the subjects quietly had their eyes open and closed. A nice rhythmic and balanced wave pattern was visible in both groups in the form of alpha waves (8-12 Hz waves, which mainly occur with relaxation). However, the peak frequency of this rhythm was lower in the burnout group. This points to a lower willingness or ability to make mental efforts.. The beta rhythm, the fast little brain waves associated with a waking state, were also smaller. According to the researchers, this points to reduced activation of the cortex, the outermost layer of the large brain. In burnout patients there were - unlike those in depression - no differences in frontal EEG activity between the left and right hemisphere.. A second test, in which the participants listened to a series of tones that was occasionally interrupted by a different tone, also showed clear differences ...

The present study provides a series of observations supporting the view that the VM thalamic nucleus is a critical part of the network contributing to the emergence of the exaggerated high-beta range oscillatory activity in the MCx and BG of the hemiparkinsonian rat during treadmill walking. The transition from inattentive rest to treadmill walking induced an increase in high beta range (30-36 Hz) activity in the VM thalamus of the dopamine cell-lesioned hemisphere relative to the nonlesioned hemisphere. This was accompanied by increases in the synchronization of VM spikes to the local and cortical high beta LFP activity and increased coherence between LFP activity in the VM, MCx and SNpr in the same frequency range. In addition, high beta range LFP power and coherence in the MCx and SNpr were dramatically reduced by blocking GABAA receptor-mediated input into the VM through infusion of the GABAA antagonist picrotoxin or by inhibiting VM activity through local infusion of the GABAA agonist ...

Response time variability (RTV) during cognitive tasks is an indicator of sustained attention abilities in healthy adults. While brain networks that are related to sustained attention abilities have been identified, the relationship between variance in activity in these networks and RTV has seldom been explored. In the present study, we investigated the relationship between variance in activity in key attentional areas and RTV. Forty-four healthy young adults performed a visual sustained attention task while undergoing electroencephalography. We found that variability in the spectral power of parietal beta oscillations, bilaterally, was positively correlated with RTV, while beta power in right parietal electrodes was negatively correlated with RTV. Moreover, beta power was uncorrelated with beta variability, but multiple regression showed that the two interacted to predict RTV, such that high beta power and low variability were better indicators of low RTV than either measure alone. Given the ...

The speed with which one reacts to an imperative signal depends on the extent to which preceding cues predict that command. When reliable warning cues are available, the processing of the imperative stimulus can be favoured and responses partially pre-prepared, leading to shorter reaction times. Here we seek evidence for involvement of the human basal ganglia in the exploitation of behaviourally relevant predictive cues. To this end, local field potentials (LFPs) were recorded in the region of the subthalamic nuclei of parkinsonian patients during the performance of a pre-cued reaction task in which the cue either predicted or failed to predict the demands of the imperative signal. We demonstrate that LFP activity in the beta frequency band ( approximately 20 Hz) is modulated by the behavioural relevance of the external cue. The findings suggest that, first, the subthalamic nucleus is involved in mediating or facilitating the response advantage derived from predictive cues in humans and, secondly,

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

Human brain oscillations occur in different frequency bands that have been linked to different behaviours and cognitive processes. Even within specific frequency bands such as the beta- (14-30 Hz) or gamma-band (30-100 Hz), oscillations fluctuate in frequency and amplitude. Such frequency fluctuations most probably reflect changing states of neuronal network activity, as brain oscillations arise from the correlated synchronized activity of large numbers of neurons. However, the neuronal mechanisms governing the dynamic nature of amplitude and frequency fluctuations within frequency bands remain elusive. Here we show that in acute slices of rat prefrontal cortex (PFC), carbachol-induced oscillations in the beta-band show frequency and amplitude fluctuations. Fast and slow non-harmonic frequencies are distributed differentially over superficial and deep cortical layers, with fast frequencies being present in layer 3, while layer 6 only showed slow oscillation frequencies. Layer 5 pyramidal cells and

This model was designed to study the impact of H-currents on the dynamics of cortical oscillations, and in paticular on the occurrence of high and low amplitude episodes (HAE, LAE) in network oscillations. The H-current is a slow, hyperpolarization-activated, depolarizing current that contributes to neuronal resonance and membrane potential. We characterized amplitude fluctuations in network oscillations by measuring the average durations of HAEs and LAEs, and explored how these were modulated by trains of external spikes, both in the presence and absence of H-channels. We looked at HAE duration, the frequency and power of network oscillations, and the effect of H-channels on the temporal voltage profile in single cells. We found that H-currents increased the oscillation frequency and, in combination with external spikes, representing input from areas outside the network, strongly decreased the synchrony of firing. As a consequence, the oscillation power and the duration of episodes during which ...

A few days ago, Steve Mason posted a message on the website for King Biscuit Time, the side project he started in 1999 while still a member of the Beta Band.

We used LFP recordings from 252-channel ECoG arrays covering large parts of the left hemispheres of two macaques to analyze the interaction between top-down and bottom-up influences, both quantified by GC. Top-down influences were assessed between area 7a at the top of the visual hierarchy and V1 at the bottom. Bottom-up influences were assessed between V1 and V4, a known feedforward pathway carrying stimulus driven input. 7A-to-V1 GC showed a beta-band peak, which did not require visual stimulation and thus was endogenously generated, which was significantly larger in the 7A-to-V1 than the V1-to-7A direction, and which increased with selective attention. V1-to-V4 GC showed a gamma-band peak, which was stimulus driven, which was significantly larger in the bottom-up than the top-down direction, and which also increased with selective attention. JC between top-down beta-band influences and bottom-up gamma-band influences revealed a positive cross-frequency interaction. This interaction was ...

N2 - Parkinsons disease (PD) is characterized by pathological spontaneous beta oscillations (13 Hz-35 Hz) often observed in basal ganglia (BG) composed of subthalamic nucleus (STN) and globus pallidus (GPe) populations. From the viewpoint of dynamics, the spontaneous oscillations are related to limit cycle oscillations in a nonlinear system; here we employ the bifurcation analysis method to elucidate the generating mechanism of the pathological spontaneous beta oscillations underlined by coupling strengths and intrinsic properties of the STN-GPe circuit model. The results reveal that the increase of inter-coupling strength between STN and GPe populations induces the ...

Downloadable (with restrictions)! We compare the asymptotic relative efficiency of the Exp, Mean, and Sup functionals of the Wald, LM and LR tests for structural change analyzed by Andrews [Andrews, D.W.K., 1993. Tests for parameter instability and structural change with unknown change point. Econometrica 61, 821-856.] and Andrews and Ploberger [Andrews, D.W.K., Ploberger, W., 1994. Optimal tests when a nuisance parameter is present only under the alternative. Econometrica 62, 1383-1414.]. We derive the approximate Bahadur slopes of these tests using large deviations techniques. These show that tests based on the Mean functional are inferior to those based on the Sup and Exp when using the same base statistic. Also, for a given functional, the Wald-based test dominates the LR-based test, which dominates the LM-based one. We show that the Sup- and Mean-type tests satisfy Wieands [Wieand, H.S., 1976.

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. QEEG is a procedure that processes the recorded EEG activity from a multi-electrode recording using a computer and converts it into a brain map showing different brain waves ...

The article deals with the study of bioelectric activity of the brain in patients with various forms of migraine, complicated by status migrainosus. The EEG-mapping was performed for 32 patients with diff erent forms of migraine. The EEG registration was carried out between the attacks. Patients were calm and active and performed functional tests. The following frequency ranges were analyzed: delta rhythm, theta rhythm, alpha rhythm, beta rhythm. The spectral powers of the rhythms in the frontal, parietal, temporal, occipital regions of the cerebral hemispheres were evaluated. The results of EEG-mapping showed that patients with diff erent forms of migraine demonstrated a decrease in reactivity of the cerebral cortex as per fast-wave indices, which was even more prominent in a group of patients with migraine without aura, as well as the activation of slow-wave activity in these patients. Analysis of the data of cartograms shows that activation of slow-wave ranges and alpha frequency inhibition ...

The relationship between the electro-encephalographic (EEG) alpha and beta oscillations in the resting condition was investigated in the study. EEGs were recorded in 33 subjects, and alpha (7.5-12.5Hz) and beta (15-25Hz) oscillations were extracted with the use of a modified wavelet transform. Power, peak frequency and phase synchronisation were evaluated for both types of oscillation. The average beta-alpha peak frequency ratio was about 1.9-2.0 for all electrode derivations. The peak frequency of beta activity was within 70-90 % of the 95 % confidence interval of twice the alpha frequency. A significant (p , 0.05) linear regression was found between beta and alpha power in all derivations in 32 subjects, with the slope of the regression line being approximate to 0.3. There was no significant difference in the slope of the line in different electrode locations, although the power correlation was strongest in the occipital locations where alpha and beta oscillations had the largest power. A ...

Cortical oscillations at gamma (30-100 Hz) and beta (10-30 Hz) frequencies are implicated in cognitive tasks. Gamma and beta oscillations evoked in the hippocampal slice in vitro by tetanic stimulation can be synchronised with phase lags faster than the conduction delays expected from the distance between the stimulating electrodes. This led Traub to develop an innovative model based on networks of fast synapses using glutamate and GABA as their transmitters. While this theoretical model is feasible on the basis of the known cellular and network properties of the hippocampus, and may well apply under some experimental circumstances, we now have doubts on its application to tetanically evoked gamma rhythms because of: (1) the spatial extent of the gamma focus means that the actual distance between the oscillating populations is much less than the distance between the two stimulating electrodes (typically ~1-2mm), and (2) new evidence and ideas on the mechanism of tetanically-evoked gamma ...

Many studies have implicated the basal ganglia in the suppression of action impulses (stopping). Here, we discuss recent neurophysiological evidence that distinct hypothesized processes involved in action preparation and cancellation can be mapped onto distinct basal ganglia cell types and pathways. We examine how movement-related activity in the striatum is related to a Go process and how going may be modulated by brief epochs of beta oscillations. We then describe how, rather than a unitary Stop process, there appear to be separate, complementary Pause and Cancel mechanisms. We discuss the implications of these stopping subprocesses for the interpretation of the stop-signal reaction time-in particular, some activity that seems too slow to causally contribute to stopping when assuming a single Stop processes may actually be fast enough under a Pause-then-Cancel model. Finally, we suggest that combining complementary neural mechanisms that emphasize speed or accuracy respectively may ...

Performance improves when participants respond to events that are structured in repeating sequences, suggesting that learning can lead to proactive anticipatory preparation. Whereas most sequence-learning studies have emphasised spatial structure, most sequences also contain a prominent temporal structure. We used MEG to investigate spatial and temporal anticipatory neural dynamics in a modified serial reaction time (SRT) task. Performance and brain activity were compared between blocks with learned spatial-temporal sequences and blocks with new sequences. After confirming a strong behavioural benefit of spatial-temporal predictability, we show lateralisation of beta oscillations in anticipation of the response associated with the upcoming target location and show that this also aligns to the expected timing of these forthcoming events. This effect was found both when comparing between repeated (learned) and new (unlearned) sequences, as well as when comparing targets that were expected after short vs.

Power spectra of epicardial electrograms were studied in 13 anesthetized dogs subjected to occlusion of the left anterior descending coronary artery. Electrograms were obtained from a bipolar electrode placed on the epicardial surface of the left ventricle and recorded before and after coronary occlusion. After digitization, power spectra of the first and every 50th subsequent waveform were evaluated and compared with the power spectrum of the average waveform obtained from the baseline recording. In particular, we examined variations in relative power content in three frequency ranges: 150-250 Hz, previously shown to be directly affected by myocardial ischemia; 40-150 Hz, presumably corresponding to the fine notches and slurs on the body surface QRS; and 2-40 Hz, the low-frequency range. Apart from a mild initial rise during the first 50 heart beats, the power in the high-frequency range gradually decreased, reaching 5% of the control value at wave 500. The power in the mid-frequency range ...

When the mind enters a meditative state, one of the rewards of meditation is that the mind has truly shifted gears from a active head of Beta frequency down to a peaceful, relaxed condition of Alpha, Theta or for deep meditation, Delta. Our bodies automatically reply to each brainwave frequency (of Beta, Alpha, Theta or Delta) and turn out to be nervous or anxious (in Beta) or relaxed and peaceful (in Alpha.)
