Electrophysiological properties of frog olfactory supporting cells.

abstract：:We previously reported that stressed male Wistar rats released alarm pheromone from the perianal region, which aggravated stress-induced hyperthermia and increased Fos expression in the mitral/tufted cell layer of the accessory olfactory bulb in recipient rats. In this study, we attempted to obtain this pheromone in w...
