Document Summary

Consciousness- awareness of self (internal) and environment (external) Preconscious (sub consciousness) not currently aware, but can be easily called upon. Unconscious not aware, cannot be easily called upon. Driven by circadian rhythms-regulated by suprachiasmatic nuclei in hypothalamus. Drowsy, pineal gland releases melatonin alpha waves (slower) Stage 1 theta waves, slower; light sleep, can be easily awake. Stage 2 sleep spikes (spindles); sleep deepens. Stage 3 emergence of delta waves; sleep deepens. Stage 4 delta waves, slower and larger; unconscious. 2 models: restorative model- recharges body (hgh fountain of youth), recovery from mental physical fatigue, evolutionary model- circadian models. Information processing theory/cognitive-process dream theories- process the day, new way of thinking. Activation synthesis theory- byproducts of excess neural activity. Sedatives- barbituates (former sleeping pills), special k, rufees. Opiates- heroin, codeine, oxycontin morphine, mimics natural opiate, binds to opiate receptor and endorphin receptors, decreases da inhibition, increases release of da: relieves, blocks pain, produces euphoria, stimulants: increases neural activity.
