List of all of the study questions so far:


Introduction
1.  Why does a dog play?  Come up with plausible explanations from as many different research perspectives as you can and identify what kind of explanation each is.  Don’t focus on whether or not each explanation is correct.


Nervous System Structure
2.  Along what dimensions can the nervous system be usefully divided into smaller units, either functionally (i.e., in terms of how things work) or structurally (i.e., in terms of how it is built)?


Neurons
3.  What features of a neuron allow it to have a negative resting potential? 
4.  Why, if you stimulate the middle of an axon, will an AP travel in both directions?  Why, under normal circumstances, does an AP never travel backwards? Why don't dendrites typically use APs?

Synapse
5.  Make a list of sites in or around the synapse where a new drug "Y" might alter neurotransmission. 
6.  What are some differences between neurotransmitters and drugs that resemble them chemically?

Drugs
7.  How does the study of heroin addicts support the idea that drugs simultaneously affect multiple brain systems that underlie our feelings and behavior?  
8. What factors affect how much a person responds to a given amount of a drug on any one occassion?

Development
9.  Evaluate the statement that "having a gene for behavior X means that it is inevitable a person will exhibit behavior X." 10.  Describe a number of developmental processes that might influence how large a neural structure is in adulthood.
