Basolateral to Central Amygdala Neural Circuits for Appetitive Behaviors

Basolateral amygdala (BLA) principal cells are capable of driving and antagonizing behaviors of opposing valence. BLA neurons project to the central amygdala (CeA), which also participates in negative and positive behaviors. However, the CeA has primarily been studied as the site for negative behavi...

description Basolateral amygdala (BLA) principal cells are capable of driving and antagonizing behaviors of opposing valence. BLA neurons project to the central amygdala (CeA), which also participates in negative and positive behaviors. However, the CeA has primarily been studied as the site for negative behaviors, and the causal role for CeA circuits underlying appetitive behaviors is poorly understood. Here, we identify several genetically distinct populations of CeA neurons that mediate appetitive behaviors and dissect the BLA-to-CeA circuit for appetitive behaviors. Protein phosphatase 1 regulatory subunit 1B⁺ BLA pyramidal neurons to dopamine receptor 1⁺ CeA neurons define a pathway for promoting appetitive behaviors, while R-spondin 2⁺ BLA pyramidal neurons to dopamine receptor 2⁺ CeA neurons define a pathway for suppressing appetitive behaviors. These data reveal genetically defined neural circuits in the amygdala that promote and suppress appetitive behaviors analogous to the direct and indirect pathways of the basal ganglia. Keywords: central amygdala; basolateral amygdala; direct and indirect pathways; appetitive; reward; fear; amygdala circuit; feeding; drinking; freezing
