Note: The answers to these questions require you to expand upon what you have already learned. This is not simply a regurgitation of material covered. You will have to look in chapters in your text other than the few we covered dealing with the CNS.
1. The spinal cord can be described as a two way street (ascending and descending). Give a specific example of the source, destination, and type of signal that might each be sent from the "up" and "down" pathways.
2. Convolutions are the foldings of the brain that give it the appearance of a bunch of noodles. What is t [he advantage of your brain being configured this way?
3. In what ways is the cerebellum similar to the cerebrum?
4. What are the four generalizations of the cerebral cortex made by your book?
5. The general interpretation area of the brain involves translating one type of "knowing" into another. An example of this is supplied in your text. Give another.
6. What is the limbic system and what is its role in behavior? What are the main structures which comprise this system?
7. Mammals, say a dog or cat, for example, exhibit a number of behaviors. Which behaviors can you say with certainty are in their "nature" and which were shaped by the environment?
8. Describe some influences (at least 2, but shoot for 3) that make it so difficult to differentiate between a physiological cause of a behavior or physical trait and an environmental cause?
