Cindy brought a fake rubber snake into the lab where her rhesus monkeys lived. Most of the monkeys responded with fear vocalizations, but one did not. Cindy knew this monkey had been in a lesion experiment prior to coming to her lab, but she didn't know what type of lesion had been done. What would you tell Cindy about her monkey?
 
  a. He probably didn't have a lesion at all, as ignoring fake snakes is considered normal for rhesus monkeys.
  b. He probably had a lesion in the hippocampus of both hemispheres.
 c. He probably had a lesion in the amygdala of both hemispheres.
 d. He probably had a lesion of the ventromedial nucleus of the hypothalamus.
