PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Sleep terrors (also called night terrors) are episodes of waking abruptly from sleep, usually beginning with a panicky scream. During each episode, the person experiences intense fear and associated physical signs such as rapid breathing, accelerated heart rate and sweating.

Detailed explanation-2: -Stage 3 and 4 (delta sleep or deep sleep) Stages 3 and 4 are referred to as deep sleep or delta sleep, and it is very difficult to wake someone from them. In deep sleep, there is no eye movement or muscle activity. This is when some children experience bed wetting, sleepwalking or night terrors.

Detailed explanation-3: -Polysomnography, known as a sleep study, is a test used to diagnose sleep disorders. Polysomnography records your brain waves, the oxygen level in your blood, and your heart rate and breathing during sleep. It also measures eye and leg movements.

Detailed explanation-4: -REM rebound behavior refers to the increased frequency, depth, and intensity of rapid-eye-movement (REM) sleep following sleep deprivation or significant stressors. This activity describes the neurophysiology and hormonal processes the contribute to the phenomenon of REM rebound.

Detailed explanation-5: -Activation-Synthesis theory: This theory, proposed by Allan Hobson and Robert McCarley in 1977, suggests that sleep and dreams are a byproduct of the brain’s attempt to make sense of random neural activity.
