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.
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.
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.
Natural, restorative sleep can help stave off mental and physical decline as we age.
According to UCSF researchers, during non-REM sleep, newly learned useful neural patterns are replayed and recapped.
A new study reveals how tactile experiences are encoded in the brain as we sleep.
Study reveals how motor memory is consolidated during sleep.
Researchers report the size of the pupil fluctuates during sleep. The findings may indicate that pupil size can indicate specific sleep states.
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.
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.
