The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS).

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Cortical gamma oscillations occur alongside perceptual processes, and in proportion to perceptual salience. They have a number of properties that make them ideal candidates to explain perception, including incorporating synchronised discharges of neural assemblies, and their emergence over a fast timescale consistent with that of perception. These observations have led to widespread assumptions that gamma oscillations role is to cause or facilitate conscious perception (i.e. a positive role). While the majority of the human literature on gamma oscillations is consistent with this interpretation, many or most of these studies could equally be interpreted as showing a suppressive or inhibitory (i.e. negative) role. For example, presenting a stimulus and recording a response of increased gamma oscillations would only suggest a role for gamma oscillations in the representation of that stimulus, and would not specify what that role were. For instance, if gamma oscillations were inhibitory, then they
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
To quantify the relationship between SC and cortical oscillations by an additional coupling measure that takes phase into account, we computed the cross-frequency phase-amplitude coupling between SC and μECoG recording sites (see fig. S7). This measure quantifies the strength with which the amplitude of SC LFP oscillations is modulated by the phase of μECoG signals across all possible frequency-frequency combinations. Figure 7B displays population-averaged cross-frequency phase-amplitude spectrograms for SC-μECoG channel pairs that display significant (left) and insignificant (middle) high-frequency amplitude correlation, respectively. Cross-frequency coupling for correlated SC-μECoG channel pairs was characterized by the strong modulation of SC activity above 8 Hz by the phase of slow cortical oscillations. In contrast, uncorrelated SC-μECoG channel pairs displayed comparatively weak cross-frequency coupling (Fig. 7B, middle). The difference in cross-frequency spectra between significantly ...
TY - GEN. T1 - Optimizing spatial filters for the extraction of envelope-coupled neural oscillations. AU - Dahne, Sven. AU - Nikulin, Vadim. AU - Ramirez, David. AU - Schreier, Peter J.. AU - Muller, Klaus. AU - Haufer, Stefan. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Amplitude-to-Amplitude interactions between neural oscillations are of a special interest as they show how the strength of spatial synchronization in different neuronal populations relates to each other during a given task. While, previously, amplitude-to-Amplitude correlations were studied primarily on the sensor level, we present a source separation approach using spatial filters which maximize the correlation between the envelopes of brain oscillations recorded with electro-/magnetencephalography (EEG/MEG) or intracranial multichannel recordings. Our approach, which is called canonical source power correlation analysis (cSPoC), is thereby capable of extracting genuine brain oscillations solely based on their assumed coupling behavior ...
What are brain oscillations?. I think it is first important to recognize what brain oscillations refer to: they are small, somewhat localized fluctuations in voltage that are often measured by EEG (electroencephalogram), though they can also be measured inside the skull or inside the brain.. Most of these oscillations are also seen in the membrane potentials of individual neurons. Fast oscillations, like gamma oscillations, can also be seen in membrane potentials but are best associated with spiking activity. The cause of the skull-measured oscillations is the coordinated activity of many many neurons acting in concert. Why certain frequencies?. Many brain oscillations are created by coupling of excitation and inhibition. The gamma oscillation, for example, is most associated with interactions between excitatory neurons and particular inhibitory neurons called fast-spiking and/or parvalbumin-positive cells. The frequency of the gamma oscillation is due to the time constants and conduction times ...
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 ...
Despite the several-thousand-fold increase of brain volume during the course of mammalian evolution, the hierarchy of brain oscillations remains remarkably preserved, allowing for multiple-time-scale communication within and across neuronal networks at approximately the same speed, irrespective of b …
The nucleus accumbens is critical for reward-guided learning and decision-making. It is thought to gate the flow of a diverse range of information (e.g., rewarding, aversive, and novel events) from limbic afferents to basal ganglia outputs. Gating and information encoding may be achieved via cross-frequency coupling, in which bursts of high-frequency activity occur preferentially during specific phases of slower oscillations. We examined whether the human nucleus accumbens engages such a mechanism by recording electrophysiological activity directly from the accumbens of human patients undergoing deep brain stimulation surgery. Oscillatory activity in the gamma (40-80 Hz) frequency range was synchronized with the phase of simultaneous alpha (8-12 Hz) waves. Further, losing and winning small amounts of money elicited relatively increased gamma oscillation power prior to and following alpha troughs, respectively. Gamma-alpha synchronization may reflect an electrophysiological gating mechanism in ...
By taking such measures that in the brain wave measurement by a wearable device capable of an acoustic output and in a brain wave interface or in a brain wave monitor, noise derived from an output acoustic signal is estimated and removed from the voltage level obtained at an electrode, brain waves can be used without being affected by the noise. A brain wave measuring device comprises: a brain wave measuring unit for measuring the brain waves of the user by using a plurality of electrodes; an electroacoustic converter disposed in the vicinity of at least one electrode among the plurality of electrodes when the user wears the brain wave measuring unit and presenting an acoustic signal to the user; an amplitude envelope extraction unit for extracting the amplitude envelope of the acoustic signal presented from the electroacoustic converter; a frequency analysis unit for analyzing the frequency of the amplitude envelope extracted by the amplitude envelope extraction unit; and a noise estimation unit
The entorhinal cortex (EC) has bidirectional connections with the hippocampus and plays a critical role in memory formation and retrieval. EC is one of the most vulnerable regions in the brain in early stages of Alzheimers disease (AD), a neurodegenerative disease with progressive memory impairments. Accumulating evidence from healthy behaving animals indicates gamma oscillations (30-100 Hz) as critical for mediating interactions in the circuit between EC and hippocampus. However, it is still unclear whether gamma oscillations have causal relationship with memory impairment in AD. Here we provide the first evidence that in vivo gamma oscillations in the EC are impaired in an AD mouse model. Cross-frequency coupling of gamma (30-100 Hz) oscillations to theta oscillations was reduced in the medial EC of anesthetized amyloid precursor protein knock-in mice. Phase locking of spiking activity of layer II/III pyramidal cells to the gamma oscillations was significantly impaired. These data indicate that the
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..

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 ...
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 ...
Apparatus for and method of sensing brain waves at a position remote from a subject whereby electromagnetic signals of different frequencies are simultaneously transmitted to the brain of the subject in which the signals interfere with one another to yield a waveform which is modulated by the subjects brain waves. The interference waveform which is representative of the brain wave activity is re-transmitted by the brain to a receiver where it is demodulated and amplified. The demodulated waveform is then displayed for visual viewing and routed to a computer for further processing and analysis. The demodulated waveform also can be used to produce a compensating signal which is transmitted back to the brain to effect a desired change in electrical activity therein.
Gamma-band synchronization has been linked to attention and communication between brain regions, yet the underlying dynamical mechanisms are still unclear. How does the timing and amplitude of inputs

A mouse study has found that the apoE4 protein decreases two types of brain activity in the hippocampus that are important for memory formation: sharp wave ripples (ripples) and coincident slow gamma activity. During the ripples, prior experiences are replayed numerous times to help preserve the memory of them, and the slow gamma activity that occurs during the ripples helps to ensure that the replay of those memories is accurate.. Mice with apoE4 had fewer ripples than mice with the normal apoE3 protein, and they had less slow gamma activity during the ripples. It appears that apoE4 expression disrupts slow gamma activity during ripples, and this in turn impairs memory consolidation.. The finding points to restoring slow gamma activity in the hippocampus as a therapeutic target.. http://www.eurekalert.org/pub_releases/2016-05/gi-glt050516.php. ...
The book begins with an introduction to MATLAB, the most common programming platform in neuroscience, which is used in the book. (Readers familiar with MATLAB can skip this chapter and might decide to focus on data type or method type.) The book goes on to cover neural field data and spike train data, spectral analysis, generalized linear models, coherence, and cross-frequency coupling. Each chapter offers a stand-alone case study that can be used separately as part of a targeted investigation. The book includes some mathematical discussion but does not focus on mathematical or statistical theory, emphasizing the practical instead. References are included for readers who want to explore the theoretical more deeply. The data and accompanying MATLAB code are freely available on the authors website. The book can be used for upper-level undergraduate or graduate courses or as a professional reference.. ...
Figure 3. Standard deviation of the average band power across ages (x-axis) plotted with the average standard deviation of each band power across participants within each age (y-axis). Within-age SD was calculated by calculating the SD across participants at each given age. Ages 78+ all had two or fewer participants, so we grouped them into a single age bin. Mean within-age SD (y-axis) was calculated as the average within-age SD. Between-age SD (x-axis) was calculated by first computing the mean band power for each individual age, then calculating the SD across these values. ...
What, exactly, is a brain wave? Some stages of akasha moving? ,What does it measure, or reflect? That depends on the sector. ,Is it really a wave form The only time I perceived some (magic ones to do with someone else) in my brain, they had regular wave shape, but only as long as the other was constant on a setting, when he fuzzed to another one there were loads of energies that I did not track. Dont recall much about them, but to me those did not seem like regular wave shapes. Might depend on the area and what you do. Concerning tuning to other energies: As such some areas can be tuned to overlay with external energies, especially some of the energy sensor areas meant for such, but with artificial ranges it might be questionable if it is healthy to do that. If wishing to tune to sleeping ranges, or other stages, it might be healthier to have a consenting brain able to tune there and tune to it. That is more natural than using artificial devices ...

So, after all, they are not going to give us the money; oh dear no, but they will give us a little bit of it provided we do some work for them- provided that we build houses of which we cannot afford to pay the rent when we are back on the dole after having built them, and provided that we drain waterlogged land. Why should we drain waterlogged land, presumably for grain growing, when the granaries of the world are bursting with the wheat which its capitalistic proprietors cannot sell? But the answer is plain. The workers must WORK. That a worker, when he has produced enough foodstuffs and other commodities to last another three years, should sit back and smoke a pipe, is unthinkable-a thought too terrible to contemplate. He would become DEMORALISED ...
Our findings show that spikes from isolated single units in the hippocampus are phase locked to each other and to gamma-band oscillations in simultaneously recorded hippocampal LFPs during memory encoding. Furthermore, the magnitude of this phase locking is correlated with subsequent recognition memory performance. These results suggest that memory encoding is accompanied by enhanced coordination between hippocampal neurons.. Fell et al. (2001) previously showed that successful recognition memory encoding is correlated with increased gamma-band synchronization between local EEG oscillations in the hippocampus and rhinal cortex of human epileptic patients. The current findings extend these observations to hippocampal neurons, indicating that single units within the hippocampus synchronize the timing of their spikes to the local network oscillations during memory formation, perhaps as a mechanism by which neurons sharing similar response properties might undergo functional coupling. We also found ...
Tinnitus is the perception of a sound in the absence of a corresponding external sound source. Pathophysiologically it has been attributed to bottom-up deafferentation and/or top-down noise-cancelling deficit. Both mechanisms are proposed to alter auditory -thalamocortical signal transmission, resulting in thalamocortical dysrhythmia (TCD). In deafferentation, TCD is characterized by a slowing down of resting state alpha to theta activity associated with an increase in surrounding gamma activity, resulting in persisting cross-frequency coupling between theta and gamma activity. Theta burst-firing increases network synchrony and recruitment, a mechanism, which might enable long-range synchrony, which in turn could represent a means for finding the missing thalamocortical information and for gaining access to consciousness. Theta oscillations could function as a carrier wave to integrate the tinnitus-related focal auditory gamma activity in a consciousness enabling network, as envisioned by the ...
However, it is unknown how inhibitory neurons control these oscillations. Because brain waves are a network phenomenon, it is also not clear how the properties of individual cells are reflected in network dynamics, or whether only synaptic connections are important.. Tatjana Tchumatchenko from the Max Planck Institute for Brain Research in Frankfurt and Claudia Clopath from Imperial College London are convinced that mathematics can deepen our understanding of the phenomenon of brain waves. In their joint work, they developed a mathematical framework that models the activity of excitatory and inhibitory neurons in a network such as the human cerebral cortex.. We are able to reliably reproduce results from previous experiments using an analytical and numeric approach and our mathematical model has revealed two new conditions essential for the emergence of brain waves, says Tatjana Tchumatchenko. First, the individual inhibitory neurons must exhibit subthreshold resonance of the membrane ...
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.
The cellular diversity of interneurons in the neocortex is thought to reflect subtype-specific roles of cortical inhibition. Here we ask whether perturbations to two subtypes-parvalbumin-positive (PV+) and somatostatin-positive (SST+) interneurons-can be compensated for with respect to their contributions to cortical development. We use a genetic cell fate switch to delete both PV+ and SST+ interneurons selectively in cortical layers 2-4 without numerically changing the total interneuron population. This manipulation is compensated for at the level of synaptic currents and receptive fields (RFs) in the somatosensory cortex. By contrast, we identify a deficit in inhibitory synchronization in vitro and a large reduction in cortical gamma oscillations in vivo. This reveals that, while the roles of inhibition in establishing cortical inhibitory/excitatory balance and RFs can be subserved by multiple interneuron subtypes, gamma oscillations depend on cellular properties that cannot be compensated ...

Based on the intricate expression pattern of ErbB4 during development and in the adult brain, we decided to compare the behavioral outcomes between ErbB4−/− and PV-Cre;ErbB4 mice. Interest in identifying the potential role of PV-expressing interneurons in mediating NRG/ErbB4 effects on behavior stems from multiple observations, including (1) the extensive coexpression of PV and ErbB4 in the PFC and, albeit to a lesser extent, the hippocampus (Fisahn et al., 2009; Fazzari et al., 2010; Neddens and Buonanno, 2010); (2) the notion that PV interneurons are involved in gamma oscillations whose power is reduced in schizophrenia (Kwon et al., 1999; Wilson et al., 2008); and (3) the finding that the number of PV mRNA and protein-expressing cells is reduced in the PFC of individuals with schizophrenia (for review, see Lewis et al., 2005). Intriguingly, acute NRG-1/ErbB4 signaling potently augments the power of kainate-induced hippocampal gamma oscillations, while slices from ErbB4−/− mice exhibit ...
sciencedaily.com Figuring out how to pedal a bike and memorizing the rules of chess require two different types of learning, and now for the first time, researchers have been able to distinguish each type of learning by the brain-wave patterns it produces. These distinct neural signatures could guide scientists as they study the underlying neurobiology of how we both learn motor skills and work through complex cognitive tasks, says Earl K. Miller, the Picower Professor of Neuroscience at the Picower Institute for Learning and Memory and the Department of Brain and Cognitive Sciences, and senior author of a paper describing the findings in the Oct. 11 edition of Neuron. When neurons fire, they produce electrical signals that combine to form brain waves that oscillate at different frequencies. Our ultimate goal is to help people with learning and memory deficits, notes Miller. We might find a way to stimulate the human brain or optimize training techniques to mitigate those deficits. The neural

Many experiments showed that neurons tend to fire at some phase (usually trough) of local field potential (LFP) oscillations, such as theta or gamma rhythm. LFP is supposedly generated by a population of neurons with coherent currents induced by spikes. So there is a causal link from spiking activity to LFPs. Is there also a significant influence on the spikes directly from LFP (not via the hidden spikes that generated the LFP)?. Is it just an epiphenomenon, and or is there a possibility that it is partly a serious mechanism for neural computation?. ...
Thank you for your comments, which I understand to pertain to the broad spectrum of activity in the brain. I should perhaps have made it clearer that I was referring to just a narrow part of that spectrum, namely the gamma range of frequencies of oscillation defined by the authors in my references 5,6 and 7. These and other researchers are tentatively identifying the rhythmic and synchronised firing of certain groups of neurons in this gamma range as the neural correlate of awareness of particular objects. I propose only that mitochondria in certain circumstances might trigger this rhythmic and synchronised firing in the gamma range. The complex interaction of many nerve impulses arriving at the synapses of one neuron from other parts of the brain is something I know nothing about.

Kindergarten economics: when a person makes $ 1,000 per month and spends $ 1,200, after a while he will have problems. At first, he may find a bank that is willing to lend him the $ 200, but banks are not (totally) crazy so at one point the individual will have to cut his spending and live with the money he actually makes. The US of A as a whole has been living like the person in this example for at least a decade, continuously spending more than it is making. With the recent sub-prime crisis, this period seemed to have come to an end which is good. Americans need to spend less, save more and go back to a standard of living they can actually afford. But the Bush government and the Fed are now doing their best to prolong the good times by giving away tax checks and dramatically lowering interest rates. Which only means that the recession that will follow will be deeper, when it comes. All Bush and the Fed are doing is delaying the process of adjustment. This would have been a good time to force ...
