Sleep Stages, REM, and Dreaming

REM and Non-REM Sleep Non- REM Sleep – Stages considered N-REM (non-REM sleep) REM Sleep – Recurring sleep stage during which vivid dreams commonly occur. – Called rapid eye movement (REM Sleep) as eyes move quickly back and forth – Considered “paradoxical sleep” – Term coined by William Dement

Paradoxical Sleep During REM sleep brain wave patterns are similar to when a person is awake Pulse and breathing quickens. REM sleep is sometimes called paradoxical sleep as one’s physiology is close to that of being awake but the brainstem blocks all muscle movement

Typical Night’s REM Sleep

Sleep Through Life

Why do we dream? Information Processing Theory – Dreams serve an important memory- related function by sorting and sifting through the day’s experiences – Research suggests REM sleep helps memory storage. Physiological Function Theory – Neural activity during REM sleep provides periodic stimulation of the brain.

Why do we dream? Activation- Synthesis Theory – Dreams are the mind’s attempt to make sense of random neural firings in the brain as one sleeps. Cognitive Development Theory – Dreams part of the maturation process – Dreams reflect our knowledge – Reflection of normal cognitive development

Sleep Disorders and Sleep Problems Insomnia – Recurring problems falling asleep or staying asleep. – Sleeping pills tend to inhibit or suppress REM sleep; worsen the problem – Alcohol suppresses REM sleep; also worsens the problem – Studies show most people overestimate how long it took them to get to sleep

Sleep Disorders and Sleep Problems Sleep Apnea – Sleep disorder characterized by temporary cessations of breathing during sleep and consequent momentary reawakenings. – Tend to be loud snorers

Sleep Disorders and Sleep Problems Narcolepsy – Sleep disorder characterized by uncontrollable sleep attacks. – The sufferer may lapse directly into REM sleep, often at inopportune times. – Nervous system getting aroused tends to trigger the sleep attack

Sleep Disorders and Sleep Problems Somnambulism (Sleepwalking) – Usually starts in the deep stages of NREM sleep (Stage 4) – The sleepwalker can walk or talk and is able to see but rarely has any memory of the event.

Sleep Disorders and Sleep Problems Night Terrors – Sleep related problem characterized by high arousal and an appearance of being terrified. – Unlike nightmares, they occur during NREM 3 sleep, occur within two or three hours of falling sleep, and are seldom remembered.
