Central nucleus of the amygdala (CeA) has been known as an output region of emotional processing, such as fear emotion. However, recent development of technology allows us to dissect CeA neurons to find the additional role of CeA in feeding behavior, anxiety behavior and pain regulation. On the other hand, neuropeptide B/W receptor 1 expressing neurons (NPBWR1 neurons) have been known to localize in the CeA, but their physiological role is still unclear. In this review, I will introduce the recent findings about the variety of neurons in the CeA and explain the role of NPBWR1 neurons in the regulation of social behavior.
