New research shows that during moments of lost focus after poor sleep, the brain releases a wave of cerebrospinal fluid (CSF)-the same cleansing process that normally occurs during deep sleep. Using simultaneous EEG and fMRI scans, scientists found that these fluid pulses occur precisely when attention lapses, suggesting the brain is attempting to catch up on missed housekeeping.
