Which of the following is a true of the features of regulation of sleep and wakefulness? If an individual spends a month in a pitch-black cave, his circadian clock stops functioning. Melatonin levels are normally high during the day and low at night. The circadian process is independent of the time of day. In the homeostatic process, sleep pressure builds for each hour of wakefulness.

Sleep Physiology

Sleep is a condition of reduced muscle movement in the body. Awareness about the surroundings is reduced at the time of sleep. The body stays mildly responsive or non-responsive to external stimuli. The sleep-wake cycle is controlled by the circadian rhythm that produces a resting phase for the body.

Question

Melatonin levels are normally high during the day and low at night.

The circadian process is independent of the time of day.

In the homeostatic process, sleep pressure builds for each hour of wakefulness.

Which of the following is true of human sleep cycles? There is usually about 15 minutes between sleep cycles. Sleep cycles are random across the night. Stages 3 and 4 of slow-wave sleep mostly occur in the early morning hours (at the end of the sleep cycle). "As the night goes on, the relative length of REM sleep increases in each successive cycle."
Elevated levels of cortisol have been shown to reduce areas of the hippocampus in the brain resulting in short term memory loss in older adults. (source: Sonia J. Lupien et al. Nature Neuroscience 1, 69-73 [1998]) Exposure to long-term stress results in elevated levels of cortisol in adults. Over time, cortisol may have detrimental effects on your health. Determine the effect below that is NOT a result of long-term stress. Select one: O a. Blood pressure is elevated. O b. The body is more prone to infections. c. The breathing rate increases. Od. Blood sugar levels are elevated. Clear my choice
Melatonin is a hormone primarily released by the pineal gland at night and has long been associated with control of the sleep–wake cycle. As a dietary supplement, melatonin is often used for the short-term treatment of insomnia, For your Thread: Utilizing chapter 11, section 11.5 and additional research resources, discuss advantages and disadvantages of melatonin used as a dietary supplement compared to chemical-based sleep aids. How is the body affected by each type of sleep aid?

Part 2: Please read the following scenarios. For each scenario, identify the confound and suggest how it might be removed in a follow-up experiment. McCann and Holmes (1984) tested the hypothesis that exercise reduces depression. They randomly assigned depressed undergraduate women either to an exercise condition (attending an aerobics class a couple of times a week for ten weeks) or to a relaxation training condition (the individuals relaxed at home by watching a videotape over the same period of time). Although the results showed that the exercise group reported less depression at the end of the ten-week period than did the relaxation group, why can't the researchers conclude that exercise reduces depression?
Which of the following pairs is correctly matched? Coma – lack sleep-wake cycles Desynchronized EEG waves – high amplitude waves Caffeine – activates adenosine receptors Increased secretion of histamine from the hypothalamus – slow wave or NREM sleep
Medical researchers discover a new compound, known as Serenity, which has been shown to be effective at reducing anxiety in laboratory mice. The researchers now wish to test the compound in human subjects. Which of the following would be the hypothesis for their experiment? O People diagnosed with a General Anxiety Disorder will be given either the drug serenity or a sugar pill placebo for 6 months and then will complete a test that is used to quantify anxiety level. People given the drug Serenity will have lower scores on the Johnson-Smith Anxiety Index test then people that are given a sugar pill placebo. O Serenity will reduce anxiety in people diagnosed with a General Anxiety Disorder due to its ability to limit serotonin reuptake by neurons.
During an evening walk, jane was startled by a 4-foot alligator that splashed when she crossed a wooden bridge. Immediately, her pupils dilated, she began to perspire, and her heart rate accelerated. By the time jane returned home, her arousal level had returned to normal. Which system in jane body controlled her responses? Autonomic nervous system Central nervous system Endocrine system Limbic system or Somatic nervous system
Thermoreceptors in the hypothalamus sense the temperature of the blood. When blood temperature begins to decrease, the hypothalamus releases TRH, which stimulates the release of TSH from the anterior pituitary gland. TSH stimulates the thyroid gland to release thyroid hormone (TH). TH stimulates an increase in body temperature, which causes the hypothalamus to decrease the release of TRH. In this reflex pathway, what is the response? A) Increased body temperature B) Increased release of TH C) Thermoreceptors D) Decreased release of TRH
