In this first intracellular study of neocortical activities during waking and sleep states, we
hypothesized that synaptic activities during natural states of vigilance have a decisive impact …

Earlier extracellular recordings during natural sleep have shown that, during slow-wave
sleep (SWS), neocortical neurons display long-lasting periods of silence, whereas they are …

To investigate the relative impact of intrinsic and synaptic factors in the maintenance of the
membrane potential of cat neocortical neurons in various states of the network, we …

In studies on preparations in which spontaneous activity is significantly reduced or
negligible, the properties of different cortical neuronal classes seem to be inflexible. But …

Neuronal circuits between the neocortex, the thalamus, the hippocampus and related
systems underlie the different states of vigilance and various paroxysmal disorders that …

The two processes of activation in thalamocortical systems exerted by mesopontine
cholinergic neurons are (a) a direct depolarization associated with increased input …

Slow waves and sleep spindles are prominent features of the EEG in non-REM sleep and
some of the neurophysiological mechanisms underlying their genesis have been elucidated …

Key points• A signature of deep sleep in the EEG is large‐amplitude fluctuation of field
potential, which reflects alternating periods of activity and silence in the thalamocortical …

Intracranial recording is an important diagnostic method routinely used in a number of
neurological monitoring scenarios. In recent years, advancements in such recordings have …

Slow-wave sleep is characterized by alternating periods of activity and silence in
corticothalamic networks. Both activity and silence are stable network states, but the …
