Slow waves are the most prominent electroencephalographic feature of non-rapid eye
movement (NREM) sleep. During NREM sleep, cortical neurons oscillate approximately once …

Consciousness never fades during waking. However, when awakened from sleep, we sometimes
recall dreams and sometimes recall no experiences. Traditionally, dreaming has been …

Sleep slow wave activity (SWA) is thought to reflect sleep need, increasing after wakefulness
and decreasing after sleep. We showed recently that a learning task involving a …

By employing transcranial magnetic stimulation (TMS) in combination with high-density
electroencephalography (EEG), we recently reported that cortical effective connectivity is …

… B: The boundaries of the box plots indicate the 25th and 75th percentiles, and the line within
the box marks the median value. Whiskers indicate the 10th and 90th percentiles. Circles …

… (B and B′) The absolute current density in the cerebral cortex is estimated with L2 Norm
at different time points and plotted together with the corresponding scalp voltage distribution (…

… (B) Cortical flat maps showing relative current density at the time points indicated by the
red … Note the difference between the first wave (A and B) where recruitment occurs from a …

Study Objectives: The mechanisms responsible for the homeostatic decrease of slow-wave
activity (SWA, defined in this study as electroencephalogram [EEG] power between 0.5 and …

… One likely source of this coordination is the thalamus, as (a) thalamic inactivation disrupts
synchrony of active state onsets [26], and (b) occasional firing of thalamocortical cells at the …

Study Objectives: The electrophysiological correlates of anesthetic sedation remain poorly
understood. We used high-density electroencephalography (hd-EEG) and source modeling to …
