In the study of the nature of sleep, which specific brain wave activity is most characteristic of Stage 3 NREM sleep?

Which of the following symptoms is a defining characteristic of cataplexy, often experienced by individuals with narcolepsy?

A key diagnostic feature of narcolepsy is the presence of SOREMPs. Which of the following best describes this phenomenon?

Which of the following biological rhythms lasts longer than \( 24 \) hours, such as the human menstrual cycle?

Research into shift work suggests that rotating shifts can be particularly disruptive. Which type of shift rotation is generally found to be less harmful to the sleep/wake cycle?

Identify the typical duration of one complete ultradian cycle of sleep in a healthy adult and name one specific stage of NREM sleep found within this cycle.

Explain the primary difference between a circadian rhythm and an infradian rhythm, providing one example of an infradian rhythm found in humans.

Analyze why REM sleep is frequently characterized as paradoxical sleep, making reference to both internal brain activity and the external state of the body.

Identify and describe two distinct characteristics of Stage 2 sleep compared to REM sleep. Your answer should include reference to brain wave patterns and physiological activity.

A longitudinal study observed the sleep patterns of three different age groups and recorded the average percentage of REM sleep per night as follows:
- Neonates (0-1 month): \( 50\% \)
- Adults (20-30 years): \( 25\% \)
- Elderly (70+ years): \( 15\% \)

Identify the trend shown in the data and use the restoration theory of sleep to explain why the requirement for REM sleep changes so significantly from infancy to old age.
