Astrocytes are important for uninterrupted slow wave sleep and brain rhythms that are essential for learning and memory, through mechanisms involving intracellular calcium signals.
A new study reports deep sleep may be critical for the immune system to strengthen its 'memories' of previously encountered pathogens.
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.
Researchers develop a method to decrypt the brain while it sleeps to reveal hidden memories.
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.
A new study reveals taking a short daytime nap can help to consolidate learning and memory of new foreign words.
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.
Using electrical fields to simulate slow wave sleep, researchers enhance memory.
