The Sleep Slow Oscillation as a Traveling Wave
TLDR
It is shown here that each cycle of the slow oscillation is a traveling wave, which provides a blueprint of cortical excitability and connectivity and may play a role in spike timing-dependent synaptic plasticity during sleep. Expand
Breakdown of Cortical Effective Connectivity During Sleep
TLDR
The fading of consciousness during certain stages of sleep may be related to a breakdown in cortical effective connectivity, as measured by transcranial magnetic stimulation and high-density electroencephalography. Expand
Local sleep and learning
TLDR
It is shown that sleep homeostasis indeed has a local component, which can be triggered by a learning task involving specific brain regions, and that the local increase in SWA after learning correlates with improved performance of the task after sleep. Expand
Electromagnetic fields, such as those from mobile phones, alter regional cerebral blood flow and sleep and waking EEG
TLDR
Results show for the first time that pm‐EMF alters waking rCBF and pulse modulation of EMF is necessary to induce waking and sleep EEG changes and may provide a new, non‐invasive method for modifying brain function for experimental, diagnostic and therapeutic purposes. Expand
Arm immobilization causes cortical plastic changes and locally decreases sleep slow wave activity
TLDR
If a subject's arm is immobilized during the day, motor performance deteriorates and both somatosensory and motor evoked potentials decrease over contralateral sensorimotor cortex, indicative of local synaptic depression, suggesting cortical plasticity is linked to local sleep regulation without learning in the classical sense. Expand
Source modeling sleep slow waves
TLDR
High-density EEG (hd-EEG) source modeling is used to show that individual spontaneous slow waves have distinct cortical origins, propagate uniquely across the cortex, and involve unique subsets of cortical structures. Expand
Reduced sleep spindle activity in schizophrenia patients.
TLDR
The deficit in sleep spindles in schizophrenia subjects may reflect dysfunction in thalamic-reticular and thalamocortical mechanisms and could represent a biological marker of illness. Expand
A direct demonstration of cortical LTP in humans: A combined TMS/EEG study
TLDR
A new approach based on combined rTMS/high-density electroencephalography (hd-EEG) to obtain direct, noninvasive evidence for LTP in humans, which provides a direct demonstration in humans of LTP induced by rT MS. Expand
Mapping of Cortical Activity in the First Two Decades of Life: A High-Density Sleep Electroencephalogram Study
TLDR
Sleep SWA assessments may be used as a clinical tool to detect aberrations in cortical maturation because changes in the topography of SWA during sleep parallel neuroimaging study findings indicating cortical m maturity starts early in posterior areas and spreads rostrally over the frontal cortex might reflect the underlying processes of cortex maturation. Expand
Sleep homeostasis and cortical synchronization: III. A high-density EEG study of sleep slow waves in humans.
TLDR
In the human EEG, the decline of SWA during sleep is accompanied by changes in slow-wave parameters that were predicted by a computer model simulating a homeostatic reduction of cortical synaptic strength. Expand
