Detailed explanation-1: -These signals come in the form of chemicals called neurotransmitters. When neurons in the arousal areas are active, the cortex remains activated and we stay awake. One area of the brain that promotes arousal is the tuberomammillary nucleus (TMN).
Detailed explanation-2: -What happens to people who are selectively deprived of slow-wave sleep for several nights in a row? They make up for the lost slow-wave sleep when allowed to sleep normally again.
Detailed explanation-3: -REM Sleep. As mentioned earlier, REM sleep is marked by rapid movements of the eyes. The brain waves associated with this stage of sleep are very similar to those observed when a person is awake, as shown in Figure SC. 11, and this is the period of sleep in which dreaming occurs.
Detailed explanation-4: -Sleep is a unique state of consciousness; it lacks full awareness but the brain is still active. People generally follow a “biological clock” that impacts when they naturally become drowsy, when they fall asleep, and the time they naturally awaken.
