The brain network organization during sleep onset after deprivation
Objective: Aim of the present study is to investigate the alterations of brain networks derived from EEG
analysis in pre- and post-sleep onset conditions after 40 h of sleep deprivation (SD) compared to sleep
onset after normal sleep in 39 healthy subjects.
Methods: Functional connectivity analysis was made on electroencelographic (EEG) cortical sources of
current density and small world (SW) index was evaluated in the EEG frequency bands (delta, theta,
alpha, sigma and beta).
