Definition
Involved in emotional responses
-region of the amygdala that receives info from the basolateral division and projects to other parts of the brain

What kind of response occurs when there is a (1) lesion of the CE, (2) stimulation of the CE, and (3) if the CE is removed?
Definition
1) no response
2) show signs of fear
3) unable to be classically or operantly conditioned
