Pathways through the amygdala mediating different CS-evoked behaviors. A, The expression of CS-evoked reactions, such as freezing, depends LA, BA, and long-range projections arising from CeA. B, The expression of CS-evoked actions, such as avoidance, also depends on LA and BA. However, the necessary amygdalar outputs arise directly from BA. CS-evoked reactions are known to require CeA projection targets, such as periaqueductal gray, while CS-evoked actions require the BA projection to NAccSh.
