The brain network organization during sleep onset after deprivation

Aim of the present study is to investigate alterations brain networks derived from EEG analysis in pre- and post-sleep onset conditions after 40 h sleep deprivation (SD) compared normal 39 healthy subjects. Functional connectivity was made on electroencelographic (EEG) cortical sources current density small world (SW) index evaluated frequency bands (delta, theta, alpha, sigma beta). Comparing vs. a night SD significant decrease SW delta theta condition found together with an increase band. pre-sleep versus decreased beta band evidenced. Brain functional network architecture influenced by different ways. topology during wake resting state needs be further explored reveal SD-related changes order prevent possible negative effects behaviour function wakefulness. The modulations as revealed could used altered balance between integration segregation processes SD.
