Hypothesized anatomical pathways mediating BLA and MeA effects on autonomic outflow. Simplified direct connections are illustrated without indirect multisynaptic circuits. The BLA has limited interaction with cell groups providing direct input to preganglionic neurons; however, the region sends excitatory projections to GABAergic cells in the BST and CeA. The MeA sends predominantly GABAergic projections to the BST, mPOA, and PH, although the neurochemistry of post-synaptic targets has not been directly investigated. See text for references. BLA: basolateral amygdala, BST: bed nucleus of the stria terminalis, CeA: central amygdala, DMV: dorsal motor nucleus of the vagus, NA: nucleus ambiguus, IML intermediolateral cell column, MeA: medial amygdala, mPOA: medial preoptic area, PH: posterior hypothalamus, Glu: glutamate, ACh: acetylcholine.
