Monitoring sleep spindles in sheep may one day translate to sleep based diagnosis of neurodegenerative diseases in humans.
Deep sleep restores the medial prefrontal cortex mechanisms that restore emotion. This lowers emotional and physiological reactivity, preventing the escalation of stress and anxiety.
Study reinforces and explains the links between sleep deprivation and neurodegenerative diseases, researchers say.
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 sheds additional light on how the brain consolidates memory during sleep. Researchers report rapid fluctuations in gamma band activity in the hippocampus during nREM sleep helps facilitate memory reactivation.
A new study MEG study reveals our ability to learn during slow wave sleep is limited.
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.
People with insomnia have greater brain activity in regions associated with conscious awareness during NREM sleep, researchers report.
