Study Notes
- Sleep disorders include narcolepsy, REM Behaviour Disorder, sleepwalking, and violence during sleep.
- Narcolepsy is characterized by frequent periods of sleepiness during the day and a lack of hypothalamic cells that produce and release orexin.
- REM Behaviour Disorder involves moving around vigorously during REM sleep and is associated with deficient GABA.
- Sleepwalking involves complex movements during NREM sleep and may be caused by sleep deprivation, stress, or alcohol.
- Sleep deprivation has widespread consequences on the brain and cognition, including reduced functional connectivity of the amygdala and executive control regions, explicit learning and memory problems, and inhibition of neurogenesis and long-term potentiation.
- Chronic sleep deprivation can lead to a shrinkage of the hippocampus.
- SD is associated with lower academic performance in students.
- Violence during sleep is associated with several sleep disorders, including RBD and NREM parasomnia.
- Congenitally blind people and cats with lesions to the visual cortex still exhibit REM sleep.
- Stimulation of the brainstem can induce seemingly complex behaviors of an evolutionary nature.
