Sex difference in the substance P-immunoreactive innervation of the medial nucleus of the amygdala.
Discrete fields of substance P-immunoreactive fibers are present within the posterior dorsal division of the medial nucleus of the amygdala and the posterior medial bed nucleus of the stria terminalis in adult male and female rats. We previously reported a sex difference in the extent of this innervation of the bed nucleus. In the present study, we have replicated our earlier finding and found an equally dramatic sex difference in the amygdala. Morphometry revealed that the areas of dense staining in both the medial amygdala and the medial bed nucleus were more than twice as large in male brains.
