Question 1

what are 4 different methods of studying the nervous system

Answer 1

1. case studies
   - events that occured naturally and using these to develop hypotheses that can be tested
2. screens
   - searching fo ranatomical structures, proteins, neurons, genes that could play a role in subject of interest
3. descriptions
   - using techniques that allow a scientist to observe the NS without manupilation
   - obseravtions
4. manipulations
   - testing a hypothesis by determining the effect of an independet variable on a dependent variable

Question 2

why arent case studies considered true experiemnts

Answer 2

because no variables are controlled

Question 3

what are the two common types of manipulation experiments

Answer 3

loss of function

gain of function

Question 4

loss of function is also called a ________ experiment

• a part of the NS is ______ to determine if it is needed for a certain process
• the _______ variable is the loss of the structure
• the _______ variable is the effect on another aspect of the NS

Answer 4

necessity
indepdent
dependent

Question 5

what is a rescue experiment

Answer 5

a follow up for loss of function experiment where the removed part is put back in

Question 6

gain of function:

• also called __________ experiment
• aspect of the NS is _____ relative to normal levels

Answer 6

sufficiency
