Gating in cerebral networks

Neuronal processes and cognitive functions in brain-active states of waking and REM sleep, and Neuronal substrates of some mental disorders.

Thalamocortical oscillations: local control of EEG slow waves.

A description of the three states of vigilances is provided followed by a detailed review of major brain rhythms present in the thalamocortical system, ranging from very slow to very fast oscillations.

Cellular mechanisms of a synchronized oscillation in the thalamus.

Reduction of gamma-aminobutyric acidA (GABAA) receptor-mediated inhibition markedly enhanced GABAB inhibitory postsynaptic potentials in relay cells and subsequently generated a slowed and rhythmic population activity resembling that which occurs during an absence seizure.

Synchronized activities of coupled oscillators in the cerebral cortex and thalamus at different levels of vigilance.

In vivo multi-site recordings from a variety of neocortical areas and related thalamic nuclei in cat demonstrate that corticofugal volleys are effective in synchronizing fast and low-frequency oscillations in thalamocortical networks, characterizing activated and de-afferented states.

Control of Spatiotemporal Coherence of a Thalamic Oscillation by Corticothalamic Feedback

Results indicate that the global coherence of thalamic oscillations is determined by corticothalamic projections.

Coherent Activities in Corticothalamic Networks During Resting Sleep and Their Development Into Paroxysmal Events

Three types of sleep rhythms are generated by thalamic and neocortical synaptic networks and through the interplay of voltage-gated conductances of thalamocortical neurons, and multi-isite recordings indicate that long-lasting inhibitory periods are effective in timing the sleep rhythms.

Partial and full synchrony of thalamic spindle oscillations

The rhythmogenesis of spindle sleep oscillations in large neural network models is investigated and it is found that in the fully connected RE+TC network, the RE cells burst in full synchrony while the TC cells segregate into clusters.

Network modulation of a slow intrinsic oscillation of cat thalamocortical neurons implicated in sleep delta waves: cortically induced synchronization and brainstem cholinergic suppression

This study proposes that the potentiating influence of the corticothalamic input results from the engagement of two GABAergic thalamic cell classes, reticular and local-circuit neurons, and proposes a progressive hyperpolarization of thalamocortical neurons with the deepening of the behavioral state of EEG-synchronized sleep.
