Story summary

Massachusetts Institute of Technology (MIT) researchers report that sleep-deprived brains experience attentional failures, with brief zoning-out moments.
The study notes cerebrospinal fluid (CSF) flows in and out of the brain, similar to patterns seen during deep sleep.
Sleep deprivation also causes slower breathing and heart rate.
