Feeding can be inhibited by multiple cues, including those associated with satiety, sickness or unpalatable food. How such anorexigenic signals inhibit feeding at the neural circuit level is incompletely understood. While some inhibitory circuits have been identified, it is not yet clear whether distinct anorexigenic influences are processed in a convergent or parallel manner. The amygdala central nucleus (CEA) has been implicated in feeding control, but its role is controversial. The lateral subdivision of CEA (CEl) contains a subpopulation of GABAergic neurons, marked by protein kinase C-δ. Here we show that CEl PKC-δ+ neurons in mice are activated by diverse anorexigenic signals in vivo, required for the inhibition of feeding by such signals, and strongly suppress food intake when activated. They receive pre-synaptic inputs from anatomically distributed neurons activated by different anorexigenic agents. These data suggest that CEl PKC-δ+ neurons constitute an important node that mediates the influence of multiple anorexigenic signals.
