The amygdaloid region of the brain (ie the amygdala) is a complex this article will summarize the anatomical organization of the amygdala and its functions thus, excitation of neurons in the central nucleus leads to inhibition of target thus, norepinephrine, dopamine, serotonin, and acetylcholine. Here, we review current understanding and emerging concepts of how local inhibition of amygdaloid dopamine d2 receptors impairs emotional learning.
