Q

A rat is given two weeks of daily trials in a T maze to turn left to find food. Before a probe trial its caudate is inactivated. At the choice point during a probe trial the rat most likely will?
A) Turn left
B) Turn right
C) Both equally likely to turn left or right.

A

B) Turn right
Hull Rats (S-R rats)
This is because the rat has been trained to turn left to find food. During a probe trial the caudate is inactivated so it won’t rely on its S-R behavior and instead will turn the opposing direction??? (ASK ABOUT THIS ONE)

Q

A rat in placed in one arm of a maze in which it receives a very large amount of food. Next it is placed in another arm in which it receives no food. Inactivation of which structure with lidocaine before the learning trials would most likely disrupt learning of which place it prefers
A) The hippocampus
B) The caudate
C) The amygdala
D) None of the above

A

A) The amygdala
Because the rat was likely overwhelmed when it was given the conditions of either a surplus of food or too little food. Thus this is an emotionally loaded memory. Thus if the amygdala (emotion processing center of memory) was diruspted then the learning would also be disrupted.
