| Research Abstract |
Using vesicular GABA transporter (VGAT)-Venus transgenic mice, in which GABAergic neurons are labeled with the Venus fluorescent protein, the immunohistochemical characterization of GABAergic neurons in the amygdala was performed. As a result, nerve terminal-like signals of somatostatin (SST) and vasoactive intestinal peptide (VIP) in the central nucleus of the amygdala were observed. These results suggest that SST and VIP have unique roles in regulation of extinction of fear memory.
