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 reports on a link between lack of restorative sleep and an accumulation of amyloid beta.
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.
A new study reveals how tactile experiences are encoded in the brain as we sleep.
According to UCSF researchers, during non-REM sleep, newly learned useful neural patterns are replayed and recapped.
Researchers report transcranial alternating current stimulation applied during sleep can help accelerate learning, memory and skill acquisition.
Sleep spindles assist with the processing of relevant memories during sleep and help boost memory consolidation, researchers report.
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.
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.
