Cortical and thalamic cellular correlates of electroencephalographic burst-suppression
TLDR
The assumption that full-blown burst-suppression is achieved through virtually complete disconnection in brain circuits implicated in the genesis of the EEG is corroborated by the revival of normal cellular and EEG activities after volleys setting into action thalamic and cortical networks.About:

General anesthesia, sleep, and coma
TL;DR: This review discusses the clinical and neurophysiological features of general anesthesia and their relationships to sleep and coma, focusing on the neural mechanisms of unconsciousness induced by selected intravenous anesthetic drugs.
Journal ArticleDOI
Corticothalamic resonance, states of vigilance and mentation.
TL;DR: In vivo experiments using simultaneous intracellular recordings from thalamic and cortical neurons show that short-term plasticity processes occur after prolonged and rhythmic spike-bursts fired by thalamo- neocortical neurons during slow-wave sleep oscillations.

General anesthesia, sleep and coma
TL;DR: A review of the clinical and neurophysiological features of general anesthesia and their relationship to sleep and coma is presented in this article, focusing on the neural mechanisms of unconsciousness induced by selected intravenous anesthetic drugs.

Cellular Basis of EEG Slow Rhythms: A Study of Dynamic Corticothalamic Relationships
D Contreras,Mircea Steriade +1 more
TL;DR: During low-frequency oscillatory states, characteristic of slow-wave sleep, neocortical and thalamic neurons display phase relations that are restricted to narrow time windows, and that synchronization results from a generalized inhibitory phenomenon.
Journal ArticleDOI
Impact of network activities on neuronal properties in corticothalamic systems.
TL;DR: The analysis of various oscillatory types leads to the conclusion that in the intact brain, there are no "pure" rhythms, generated in simple circuits, but complex wave sequences that result from synaptic interactions in corticocortical and corticothalamic neuronal loops under the control of activating systems arising in the brain stem core or forebrain structures.

A novel slow (< 1 Hz) oscillation of neocortical neurons in vivo: depolarizing and hyperpolarizing components
TL;DR: A novel slow oscillation in intracellular recordings from cortical association areas 5 and 7, motor areas 4 and 6, and visual areas 17 and 18 of cats under various anesthetics is described and synchronous inhibitory periods in both neurons are demonstrated.

Electrophysiological properties of guinea-pig thalamic neurones: an in vitro study.
H Jahnsen,Rodolfo R. Llinás +1 more
TL;DR: The electroresponsive properties of guinea‐pig thalamic neurones were studied using an in vitro slice preparation and a rather stereotyped onset firing rate was observed due to the presence of the l.t.s.p. and the plateau potential.

Properties of a hyperpolarization-activated cation current and its role in rhythmic oscillation in thalamic relay neurones.
TL;DR: Results indicate that Ih is carried by both Na+ and K+ ions, which is consistent with the extrapolated reversal potential of ‐43 mV, and contributes substantially to the resting and active membrane properties of thalamocortical relay neurones.
Journal ArticleDOI
Electrophysiological properties of neocortical neurons in vitro
TL;DR: The array of passive and active membrane behavior observed in the slice suggests that cortical neurons may be differentiated by specific functional properties as well as by their extensive morphological diversity.

Intracellular analysis of relations between the slow (< 1 Hz) neocortical oscillation and other sleep rhythms of the electroencephalogram
TL;DR: The data indicate that the thalamus is not essentially implicated in the genesis of the slow rhythm, and through the contralateral thalamocortical systems and callosal projections, also transected the corpus callosum in thalamically lesioned animals, and still recorded theslow rhythm in cortical neurons.
