The notion that learning a conditioned emotional response to a tone involves long-term potentiation is supported by studies in which
A) cells of the amygdala do not show evidence of long-term potentiation.
B) electrical stimulation of neurons that project to the amygdala produces less overall neural firing in the amygdala.
C) a drug that blocks the NMDA receptor blocks CER learning.
D) activation of NMDA receptors impairs CER learning.
E) few NMDA receptors are found in the amygdala.

Question

Quizplus · Accepted Answer

Studies have shown that a drug that blocks the NMDA receptor, which is involved in long-term potentiation, blocks the learning of a conditioned emotional response to a tone. This suggests that long-term potentiation is involved in this type of learning. The other choices do not support this idea.
