PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Parasomnias, a category of sleep disorders, are often associated with disruptions in slow wave sleep. Sleep walking and sleep talking most often occur during periods of high delta wave activity.

Detailed explanation-2: -Scientists believe that sleepwalking occurs when the brain’s limbic region remains awake. This emits alpha waves while the cortex and hippocampus regions of the brain are in a sleep state (where delta waves are emitted).

Detailed explanation-3: -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-4: -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-5: -All the way at the bottom of the spectrum of brain waves-below theta waves-are the low, deep, slow delta waves. Both delta waves and theta waves occur when you’re asleep, but delta waves are the waves that dominate when you’re in a period of deep, restorative sleep.
