Abstract(in English) We investigated the neural circuitry of the amygdala and focused on fear conditioning, which is the most studied important function of the amygdala. Fear conditioning requires the ability to switch between fear states and to flexibly extinct and relapse established conditioning. The reciprocal inhibitory circuits play an important role in the realization of these functions. In this study, we developed hypotheses for computational functions related to fear conditioning and its extinction and relapse in the amygdala nucleus, which contains reciprocal inhibitory circuits.
