Evaluate the hypothesis that slow-wave sleep is required to rest the brain. Your answer should include the effects of sleep deprivation and of physical and mental activity on slow-wave sleep
What will be an ideal response?
Answer: All vertebrates sleep, and sleep deprivation can be fatal for some animals. Sleep deprivation in humans can produce visual hallucinations and difficulty in concentration. During slow-wave sleep, brain activity declines, and it appears that slow-wave sleep is important for cognitive functioning. Although physical exertion (increase or decrease) has little effect on slow-wave sleep, mental exertion produces an increase in subsequent slow-wave sleep.
