Dreams that appear to be simultaneously realistic and bizarre help our brains learn and extract generic concepts from previous experiences, a new study reports.
Study identifies a key role the brainstem neurotensinergic neurons play in non-REM sleep regulation.
Study reveals as we sleep, cerebrospinal fluid pulses in the brain in rhythmic patterns.
Using optogenetics to dampen delta waves of rats during sleep resulted in weaker memory reactivation and promoted forgetting. The findings could have significant implications for treating PTSD in humans.
Study reinforces and explains the links between sleep deprivation and neurodegenerative diseases, researchers say.
A new study reveals people fall asleep faster when being rocked. Additionally, they showed improvements in memory consolidation and spent more time in non-REM sleep.
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 identifies two genes which regulate how much we dream. The genes, Chrm1 and Chrm3, play a key role in regulating REM sleep and function in different ways.
Researchers report transcranial alternating current stimulation applied during sleep can help accelerate learning, memory and skill acquisition.
Researchers have created a new model that may help explain how different sleep patterns may help us to solve problems. The study reveals non-REM sleep helps us categorize information, where as REM sleep helps us to draw unexpected connections between information we have been exposed to.
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.
