NREM stage 3 sleep is often referred to as deep sleep or slow-wave sleep because this stage is characterized by low frequency (less than 3 Hz), high amplitude delta waves (Figure 4.10).These delta waves have the lowest frequency and highest amplitude of our sleeping brain wave patterns. The brainstem, particularly the pons and midbrain, and the hypothalamus are key areas of the brain that control REM sleep with hormone secreting “REM-on” and “REM-off” cells.

Stimuli are encoded within milliseconds; however, the long-term … Rapid eye movement, or REM sleep, is when you typically dream. REM sleep is often called paradoxical sleep because in this sleep cycle, the sleeper is difficult to wake despite displaying the brain waves connected with waking.
