Simulation of neural oscillations at 10 Hz. Upper panel shows spiking of individual neurons (with each dot representing an individual action potential within the population of neurons), and the lower panel the local field potential reflecting their summed activity. Figure illustrates how synchronized patterns of action potentials may result in ...
This characteristic is true for fibers without neural input signals, such as pacemaker neurons, as mentioned previously, [2] and cortical pyramidal neurons that have highly-irregular firing pattern. [6] Noise generally hinders neural performance, but recent studies show, in dynamical non-linear neural networks, this statement does not always ...
Recurrent thalamo-cortical resonance or Thalamocortical oscillation is an observed phenomenon of oscillatory neural activity between the thalamus and various cortical regions of the brain. It is proposed by Rodolfo Llinas and others as a theory for the integration of sensory information into the whole of perception in the brain .
It has been suggested that one integral facet of brain dynamics underlying conscious thought is the brain's ability to convert seemingly noisy or chaotic signals into predictable oscillatory patterns. [2] In EEG oscillations of neural networks, neighboring waveform frequencies are correlated on a logarithmic scale rather than a linear scale. As ...
An oscillatory neural network (ONN) is an artificial neural network that uses coupled oscillators as neurons. Oscillatory neural networks are closely linked to the Kuramoto model, and are inspired by the phenomenon of neural oscillations in the brain. Oscillatory neural networks have been trained to recognize images. [1]
Brainwave entrainment is a colloquialism for 'neural entrainment', [25] which is a term used to denote the way in which the aggregate frequency of oscillations produced by the synchronous electrical activity in ensembles of cortical neurons can adjust to synchronize with the periodic vibration of external stimuli, such as a sustained acoustic ...
Corticomuscular coherence relates to the synchrony in the neural activity of brain's cortical areas and muscle. The neural activities are picked up by electrophysiological recordings from the brain (e.g. EEG, MEG, ECoG, etc.) and muscle . It is a method to study the neural control of movement.
The linearized system exhibits subthreshold decaying oscillations whose frequency increases as increases. At a critical value β ∗ {\displaystyle \beta ^{*}} where the oscillation frequency is high enough, bistability occurs in the ( u , v ) {\displaystyle (u,v)} system: a stable, spatially independent, periodic solution (bulk oscillation ...
