Your sleep history during middle age may predict Alzheimer's pathology later in life. A decrease in sleep quality between 50 and 70 years of age is associated with higher levels of tau and amyloid beta in the brain. Changes in brain activity and quality of sleep could be a biomarker for Alzheimer's disease.
Researchers identify the sleep mechanism which enables the brain to consolidate emotional memory. Additionally, they discovered a popular sleep medication heightens the response to and recollection of negative memories.
Infants produce sleep spindles every 10 second, whether in REM or non-REM sleep. Sleep spindles and twitching are synchronized, allowing for twitch reactions to occur during non-REM sleep in infants.
NMDA receptor hypofunction is involved in the reduction of sleep spindles and delta oscillations, which appear in the brain during deep natural sleep. Findings confirm the role NMDA receptors play in sleep disorders that accompany psychotic states.
Sleep spindles assist with the processing of relevant memories during sleep and help boost memory consolidation, researchers report.
Researchers explore how listening to music prior to sleep could impact how well you rest.
The reactivation of learned material during slow oscillation/sleep spindle complexes, and the precision of SO-spindle coupling predicts how strong a memory will be reactivated in the brain.
Early risers have significantly weaker sleep spindle activity than those who prefer to stay up late at night, a new study reveals.
A new study identifies lower amounts of sleep spindles can cause poor sleep patterns.
A Nature Communications study reveals the activity of dendrites increase as we sleep. This increased activity could be key to how we are able to form memories.
Monitoring sleep spindles in sheep may one day translate to sleep based diagnosis of neurodegenerative diseases in humans.
According to researchers, transcranial alternating current stimulation may help to improve memory when targeted to a specific kind of brain activity achieved during sleep.
