Researchers use electric current to destroy Brain Area A and conclude that the absence of a certain behavior is due to Brain Area
A. However, Brain Area A is not actually involved; instead a brain area that was passed through was involved in the circuit of interest. How could the researchers control for this erroneous finding?
a. sham lesions
b. conduct the experiment again on another group of animals
c. use a different path to administer the electric current
d. lesion other areas around the site of the previous lesion study
Question 2
Brain lesions:
a. include wounds like those suffered in concussions.
b. include wounds like those suffered in strokes.
c. can be experimentally created.
d. include wounds like those suffered in concussions and strokes and they can be experimentally created.
