People who are genetically predisposed to be "early birds" only take a few days to adjust to time changes as a result of daylight savings. Night owls can take over a week to adjust to the time change.
Sleep twitches help enrich the encoding of sensory information in newborn rats, laying the groundwork for later motor function.
Combining EEG data and MRI brain scans, researchers discovered how, during sleep, the hippocampus sends memory information it has stored throughout the day to the cerebral cortex, allowing for memory consolidation.
Daydreaming and mind-wandering appear to occur when parts of the brain fall asleep while other areas remain awake.
