The amygdala is an important neural structure in which long-term potentiation (LTP)plays a role in learning.Since the amygdala is part of the limbic system,which of the following is most likely mediated by LTP-related learning in the amygdala?
A) fear learning resulting in freezing behavior
B) orienting responses resulting in fight-or-flight behavior
C) anger initiation resulting in an adrenaline release
D) defensive reactions resulting in an opiate release

Question

Quizplus · Accepted Answer

The amygdala is involved in fear conditioning and the formation of fear memories. LTP in the amygdala plays a crucial role in the acquisition and consolidation of fear memory, leading to freezing behavior. Choice B is mediated by the sympathetic nervous system and does not necessarily involve the amygdala. Choice C is mediated by the hypothalamic-pituitary-adrenal (HPA) axis and does not necessarily involve the amygdala. Choice D is mediated by the endogenous opioid system and does not necessarily involve the amygdala.
