Researchers found that sleep-deprived individuals experience attentional failures coinciding with a flushing of CSF from the brain. During these lapses, physiological changes occur, including a flux of CSF out and then back in. The study suggests that the brain attempts to compensate for lost cleansing by initiating pulses of CSF flow.
