PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -In the deepest level of sleep, stage IV sleep, the predominant EEG activity consists of low frequency (1–4 Hz), high-amplitude fluctuations called delta waves, the characteristic slow waves for which this phase of sleep is named. The entire sequence from drowsiness to deep stage IV sleep usually takes about an hour.

Detailed explanation-2: -Delta waves are the slowest recorded brain waves in human beings. They are found most often in infants and young children, and are associated with the deepest levels of relaxation and restorative, healing sleep. Delta is prominently seen in brain injuries, learning problems, inability to think, and severe ADHD.

Detailed explanation-3: -The brain activity during this period has an identifiable pattern of what are known as delta waves. For this reason, stage 3 may also be called delta sleep or slow-wave sleep (SWS).

Detailed explanation-4: -Stage N3: Delta Waves The slow delta waves only occur during the deepest stage of sleep, and as such are predominant in stage N3. Delta brain waves are the slowest brain waves, measuring at 0.5 to 3 Hertz. When delta brain waves are most dominant, your brain is involved in resting and regeneration.

Detailed explanation-5: -Deep, slow brain waves known as delta waves begin to emerge during NREM stage 3 sleep-a stage that is also referred to as delta sleep. This is a period of deep sleep where any environmental noises or activity may fail to wake the sleeping person.
