- a Cerebrospinal fluid (CSF) circulates through the ventricles, provides a cushion from physical shock, carries away waste products and toxins, and carries nutritional substances/neurotransmitters to various cells.
Hydrocephalus: an enlargement of the ventricles.
- b Found mostly outside the membrane
- c The "peakedness" of the distribution.
Leptokurtic: more peaked than normal distribution
Platykurtic: flatter than normal distribution
- d in-depth observation of the behavior of one person or small group of individuals, used in interpretative clinical research and when large numbers of participants are not available.
2 drawbacks: small sample size (limit to generalizability) and susceptibility to researcher bias (researchers tend to see what they expect to see).
- e Interviews and questionnaires
Random sample: must be selected from pop. in an arbitrary way
Stratified Random Sample: specifies the percentage of people to be drawn from each population category.
Disadvantage: people may not respond to the questions truthfully.

- Potassium flowing out of the membrane inhibits the neuron making it less likely to fire (-70mV to -90mV)
- College students wrote for 20 minutes a day for three consecutive days (some wrote about emotions and the other group wrote strictly on what they did that day). Pennebaker measured both group's visits to the campus health center after the writing exercises and found that those who wrote about their emotions were healthier.
- Investigates the physical basis of psychological phenomena. (e.g., How are memories stored in the brain?)
- Metaphor: We are all runners in a race, competing for survival, sexual partners, and resources.
Methods: Mostly deductive, some experimental.
Data: Often start with a known behavior in a species and attempt to explain it on the basis of logical arguments.
- damage to the vpc interrupts connections to the limbic system and results in mood swings, loss of social inhibition and changes in personality
5 True/False questions
Hindbrain → Medulla, pons, and cerebellum
GABA → Human's with left-sided brain damage show evidence of language impairment
Electrical Gradient → The center around which the raw data tend to cluster.
Mean: average (affected by outliers)
Median: score that falls in the middle
Mode: most frequent score
Endorphins → reduce pain and elevate mood (runner's high)
Alternate Form Reliability → consistent across forms (requires that there are 2 forms of the test that are the same or very similar in terms of the number of items, time limits, content, etc.) (least popular method b/c it is difficult to come up multiple tests)
