Multiple Choice

The notion that learning a conditioned emotional response to a tone involves long-term potentiation is supported by studies in which

A) activation of NMDA receptors impairs CER learning.
B) electrical stimulation of neurons that project to the amygdala produces less overall neural firing in the amygdala.
C) CER learning is blocked when a drug prevents the insertion of AMPA receptors into dendritic spines.
D) cells of the amygdala do not show evidence of long-term potentiation.
E) few NMDA receptors are found in the amygdala.
