Document Summary

Brain structures involved in regulating sleep: no single brain system regulates sleep, many integrated systems and neurotransmitters. Sleep occurs when: the ascending reticular-activating system (aras) is inhibited. Located in the midbrain: the hypnogenic system is activated. Pons is critical for rem sleep as it contains (cid:498)sleep-on(cid:499) neurons that activate different regions of the brain that control rem sleep. Sleep and neurotransmitters: acetylcholine inhibits muscle movements during rem sleep, gaba inhibits activity in the central nervous system, serotonin, dopamine, and norepinephrine have an important role in arousal and motivation. Sleep is an interplay of multiple neural center and neurotransmitters. Effect of sleep deprivation on cognitive performance: experimental group sleep deprived, had poor performance and concentration. Insomnia: difficulty falling or staying asleep: most common sleep disorder 10%-40% of the population, biological factors genetic predisposition, psychological factors mental disorders like anxiety and depression, environmental factors drugs, lifestyle habits, travelling, night shifts.
