Serotonin-like immunoreactive fibers in the medial dorsal accessory group and the anterior fornical nucleus of the magnocellular neurosecretory system in the rat.
The area lateral to the stria medullaris and the fornix at the level of the interventricular foramen, an area known to be occupied by the medial dorsal accessory group and the anterior fornical nucleus of the magnocellular neurosecretory system, was found to be studded with serotonin (5-HT)-like immunoreactive (LI) varicosities. Double immunostaining with antisera against 5-HT and oxytocin (OXY) proved that the 5-HT-LI varicosities were in close proximity to the OXY-LI neurons in the medial dorsal accessory group and the anterior fornical nucleus. These nuclei were distributed more densely with 5-HT-LI varicosities than other cell groups in the magnocellular neurosecretory system.
