Question

Quizplus · Accepted Answer

The amygdala is important for acquiring and expressing fear responses through classical conditioning. Rats with a damaged amygdala cannot acquire a classically conditioned fear response, hence the correct answer is C.

Answer: A and B are incorrect
 There is no evidence to suggest that rats with damaged amygdala will eat anything and never become satiated, or that they will overproduce leptin and become extremely lean.

Answer: D is incorrect
 Rats with damaged amygdala have impaired fear conditioning, so they are not more easily classically conditioned to fear-inducing stimuli than rats with intact brains.
