KEY CONCEPTS
Sleep
 Preservation theory and restorative theories of when/ why we sleep.
 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.
