Using EEG to measure REM sleep allowed scientists to distinguish dreaming from wakefulness.
A new study links poor sleep quality in older adults with elevated levels of tau, a protein associated with Alzheimer's disease. Researchers report poor sleep quality later in life may be associated with declining brain health and may be an early indicator of Alzheimer's disease.
A new study sheds additional light on how the brain consolidates memory during sleep. Researchers report rapid fluctuations in gamma band activity in the hippocampus during nREM sleep helps facilitate memory reactivation.
A new study MEG study reveals our ability to learn during slow wave sleep is limited.
People with insomnia have greater brain activity in regions associated with conscious awareness during NREM sleep, researchers report.
Sleep spindles assist with the processing of relevant memories during sleep and help boost memory consolidation, researchers report.
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.
As we age, slow brain waves during non-REM sleep fail to time contact with sleep spindles efficiently, leading to a lessened ability to form new memories correctly, a new study reports.
