| Alpha | Wave when brain is deeply relaxed, passive awareness, composed. |
| Theta | Wave when brain is unconscious, deep tranquility |
| Delta | Wave when is sleepy, unaware, has deep consciousness |
| Stage 1 | Stage of sleep with Theta waves. Lasts 1-7 minutes. Has hypnagogic hallucinations (falling/floating). |
| Stage 2 | Stage of sleep with Sleep spindles and mix of waves. Lasts 10-25 minutes. Sleep talks. |
| Sleep 3-4 | Stage of sleep with Delta waves. Lasts 30 minutes. Hard to wake, nocturnal enuresis (bedwetting), somnambulism (sleep walking), night terrors |
| REM Sleep | Stage of sleep with Beta waves. Lasts 40-60 minutes. Dreams, sleep paralysis, relaxed muscle tone |
| Newborn sleep | Sleep 6-8 times a day for 16 hours (50% of sleep is REM) |
| Adult sleep | Sleep once for 8 hours (20% of sleep is REM |
| Reticular formation | Important sleep structure in brain |
| Restorative theories | Sleep promotes physiological processes that rejuvenate the body, conserve energy and resources |
| Circadian theories | Theory that sleep evolved because of survival value (less exposure to predators, conserving energy) |
| Narcolepsy | Sudden and irresistible onsets of sleep during normal waking hours |

| Narcotics | Heroin and Morphine. Used - euphoria, anxiety reduction, pain relief. Harms - infectious diseases, accidents. Rapid tolerance, decrease in response to drug with repeated use. Physical AND psychological high. Fatal overdose - high. |
| Sedatives | Barbiturates. Used - euphoria, anxiety reductions, reduced inhibitions. Harms - accidents. Rapid tolerance. Physical AND psychological high. Fatal overdose: high. |
| Stimulants | Amphetamines, cocaine. Used - elation, excitement, increased alertness and energy. Harms - sleep problems, hypertension, stroke, liver disease, heart attack. Rapid tolerance. Physical moderate, Physiological high. Fatal Overdose high. |
| Hallucinogens | LSD. Used - increased sensory awareness, euphoria, altered perceptions. Harms - accidents. Gradual tolerance. No physical, low physiological dependence. Fatal overdose low. |
| Alcohol | Depressant. Used - mild euphoria, relaxation, anxiety reduction, reduced inhibitions. Harms - accidents, liver disease, brain damage, birth defects. Moderate tolerance. Moderate physical and psychological dependence. Fatal overdose low-high. |
| Meditation | Process producing alpha and few theta waves. Produces responses similar to systematic relaxation. |
| Role Playing theory | People acting out a hypnotic subject and behave like a hypnotized person would - explains why brain waves on EEG are the same on an awake person than on hypnotized people. |
| Dissociation / highway synopsis | The splitting off of mental processes into two / more separate streams |
