Short naps of up to 60 minutes in duration do not mitigate the effects of a night of sleep deprivation, a new study reports. However, the amount of slow-wave sleep achieved during a nap was related to reduced impairments associated with sleep deprivation.
The nucleus reuniens is responsible for coordinating synchronous slow waves between the prefrontal cortex and hippocampus during sleep. The findings suggest the nucleus reuniens plays a critical role in sleep-dependant memory consolidation.
A new study published in brain reveals that just one night of sleep disruption causes an increase in amyloid beta in the brains of healthy, middle aged people. A full week of sleep disturbances leads to a build up of Tau, another protein associated with Alzheimer's and other neurodegenerative diseases. The study sheds light on why poor sleep has previously been associated with the development of Alzheimer's and other dementias.
Researchers develop a method to decrypt the brain while it sleeps to reveal hidden memories.
A new study reports teen boys who experience a greater decline in slow wave sleep have a higher risk of developing insulin resistance than those who were able to maintain their sleep.
A new study reports deep sleep may be critical for the immune system to strengthen its 'memories' of previously encountered pathogens.
