Answers

A1. REM sleep

Because it is during this stage of sleep that most vivid dreams occur, characterized by increased brain activity and rapid eye movements.

A2. Polysomnography

Polysomnography is the correct answer because it is the medical test that monitors and records sleep patterns, including brain waves, eye movements, and muscle activity.

A3. Myoclonus

Myoclonus is the correct answer because it refers to a sudden involuntary contraction of a muscle or group of muscles, which can occur during sleep.

A4. Sleep spindles

Because they are a specific type of brain wave that occurs during non-REM sleep, characterized by bursts of oscillatory brain activity.

A5. Melatonin

Melatonin is the correct answer because it is a hormone produced by the pineal gland that regulates sleep-wake cycles and helps promote restful sleep.

A6. Deep sleep

Deep sleep, also known as slow-wave sleep, typically occupies the first third of the sleep cycle and is characterized by delta wave activity on EEG; this is when the pituitary gland releases the majority of growth hormone, which plays a crucial role in tissue repair and growth.

A7. Melatonin

Because it helps signal the body when it is time to sleep and regulates the circadian rhythm.

A8. 90 minutes

Because the average sleep cycle in adults lasts about 90 minutes, encompassing different stages of sleep, including light sleep, deep sleep, and REM sleep.
