NADPH-diaphorase activity increases during estrous phase in the bed nucleus of the accessory olfactory tract in the female rat.
We investigated the presence of nitric oxide in the bed nucleus of the accessory olfactory tract (BAOT) in males, diestrous females and estrous females using NADPH-diaphorase. Our results demonstrate a significant increase in the density of the medium-stained cells in the estrous female rats suggesting that during estrous a specific subpopulation of nitrinergic cells are activated in the BAOT. This might be related to the physiological and behavioral changes that occurs in estrous.
