Researchers report the size of the pupil fluctuates during sleep. The findings may indicate that pupil size can indicate specific sleep states.
A simple actimeter device is helping researchers better understand sleep duration and quality in humans.
Contrary to a popular theory, researchers discover the brain remains connected during non-REM sleep. The study reports not all forms of communication within the cerebral cortex are disrupted during this sleep phase.
Researchers at Johns Hopkins have identified specific neurons in the zona incerta that appear to help promote sleep. The discovery could help develop new treatments for insomnia and other sleep disorders.
According to UCSF researchers, during non-REM sleep, newly learned useful neural patterns are replayed and recapped.
Using optogenetics, researchers manipulated pulses of neural activity during non REM sleep that made mice either remember of forget things they had learned. This novel study demonstrated that altering sleep spindle oscillations during sleep has an impact on memory formation and retention.
Natural, restorative sleep can help stave off mental and physical decline as we age.
Sleep may be regulated by inflammasome NLRP3, researchers report.
A new study could be the first step to understanding the biochemistry that controls the switch from sleep to wakefulness, researchers believe.
A new study reveals how tactile experiences are encoded in the brain as we sleep.
Researchers have discovered a brain circuit that governs how certain memories are consolidated in the brain during sleep.
A new study reports on a link between lack of restorative sleep and an accumulation of amyloid beta.
