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.
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.
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.
Monitoring sleep spindles in sheep may one day translate to sleep based diagnosis of neurodegenerative diseases in humans.
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 shed light on how sleep spindles help secure memory storage and reactivation.
Sleep spindles assist with the processing of relevant memories during sleep and help boost memory consolidation, researchers report.
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.
Early risers have significantly weaker sleep spindle activity than those who prefer to stay up late at night, a new study reveals.
According to researchers, transcranial alternating current stimulation may help to improve memory when targeted to a specific kind of brain activity achieved during sleep.
