Nucleus papilion neurons play an important role in eye movement during REM sleep.
21% of veterans who experience PTSD or traumatic brain injury suffer from a rare sleep condition that affects less than 1% of the general population. The condition, REM sleep behavior disorder (RBD), is characterized by an impairment of sleep-related muscle paralysis, causing people to act out dreams during REM sleep. The uncontrolled actions often cause harm to the sufferer of their partners.
REM sleep has previously been linked to memory formation. A new study reveals this sleep period may also be critical for us to forget certain memories, preventing information overload. Researchers identified a mechanism involving MCH neurons which causes us to forget information during sleep.
Researchers have identified a second gene that contributes to natural short sleep. Using optogenetics, researchers triggered neurons in the pons that express the ADRB1 gene, rousing mice from sleep. Wakefulness-promoting neurons in the pons with a mutated version of ADRB1 were more easily activated.
Near-death experiences (NDEs) including hallucinations, out-of-body sensations and time distortions, affect around 10% of people, a new study reports. 72% of people overall who experienced NDEs say their experience was unpleasant. Researchers found an association between NDEs and REM sleep intrusion into wakefulness, resulting in sleep paralysis and hallucinations.
According to a new study, the consequence of daily stress is linked to an increase in REM sleep. Researchers report the increase is associated with genes involved in apoptosis and cell survival. The findings shed light on how stress leads to mood disorders, and how changes in sleep contribute to this.
Researchers have identified key risk factors for a violent sleep disorder known as REM sleep behavior disorder. According to the study, taking antidepressants, having PTSD and anxiety disorders increases the risk for violent episodes during sleep.
A new study reports kicks and movements of unborn babies in the womb allow the child to map their bodies and assist in the eventual exploration of their surroundings.
