Sleep cycles—understand the five stages of sleep (Stage 1, stages 2-4 as one concept, and REM sleep). You do NOT need to be able to draw brain waves, but DO need to understand what happens to the brain during sleep. Refer to ppt notes: what happens in your brain to neurotransmitters and the by-products of metabolism in the brain during sleep? What role does REM sleep appear to have in memory? Hypnosis Be able to describe the state of hypnosis (Use class notes. The text is too fuzzy on this.) Therapeutic uses of hypnosis Bad/ inaccurate uses of hypnosis Drugs Neural transmission: this one is guaranteed. It WILL be on the test. - Be able to draw and label a neuron. - Be able to describe how neurotransmitters communicate messages between cells (6 steps) Three ways psychoactive drugs affect the neurons (also guaranteed) The Pleasure Pathway, and its role in drug use (class notes—see RTF outline on essign) - Alcohol: know the four brain structures that show depressed activity, and how each one affects the person who is drinking.
