People who suffer from REM behavioral disorder, a sleep disorder linked to an increased risk of developing Parkinson's disease, exhibit limited movement of their trunk during dream re-enactment.
Degeneration of neurons associated with wakefulness, and not a lack of sleep, makes Alzheimer's patients more drowsy. The degeneration of these neurons is caused by the tau protein. In PSP, the damage to the neurons was associated with symptoms of sleep deprivation.
During an upcoming symposium, researchers will discuss the neurobiology of time perception, how emotion shapes our perception of time, and the role of memory in anticipation.
Learning consolidation that occurs during sleep is a result of the learning process, and is not simply due to neural processes and brain regions associated with learning.
The fewer slow brain waves that occur in the right prefrontal cortex during sleep, the more likely a person is to indulge in risk-taking behaviors.
Researchers have identified five genes across the genome that enable efficient sleep.
Untreated obstructive sleep apnea can accelerate biological aging, but treating OSA can slow or even reverse the process.
People who experience sleep problems and attempt to alter their sleep patterns via maladaptive coping mechanisms, such as napping or using sleep aids, may experience worse quality of sleep.
Study sheds light on how various types of pulsations in the brain change while a person sleeps.
43% of children who experience insomnia continue to experience symptoms of the sleep disorder during adolescence and into adulthood.
