Recent EEG–fMRI studies have shown that different stages of sleep are associated with
changes in both brain activity and functional connectivity. These results raise the concern …

A growing body of literature suggests that changes in consciousness are reflected in specific
connectivity patterns of the brain as obtained from resting state fMRI (rs-fMRI). As …

Modern neuroimaging methods may provide unique insights into the mechanism and role of
sleep, as well as into particular mechanisms of brain function in general. Many of the recent …

Interest in time-resolved connectivity in fMRI has grown rapidly in recent years. The most
widely used technique for studying connectivity changes over time utilizes a sliding windows …

Conventional functional connectivity (FC) analysis of fMRI data derives a single
measurement from the entire scan, generally several minutes in duration, which neglects the …

Sleep staging, the process of assigning labels to epochs of sleep, depending on the stage of
sleep they belong, is an arduous, time consuming and error prone process as the initial …

Advances in neuroimaging have greatly improved our understanding of human sleep from a
systems neuroscience perspective. However, cognition and awareness are reduced during …

Resting state functional connectivity (rsFC) evaluated by detecting temporal co-variation of
BOLD signals across multiple brain regions undergoes three major changes following sleep …

Different EEG-vigilance stages from full alertness to sleep onset can be separated during
rest. Also fMRI research recently focused on the resting condition and identified several …

The transition from wakefulness into sleep is accompanied by modified activity in the brain's
thalamocortical network. Sleep-related decreases in thalamocortical functional connectivity …
