...Jorge Larriva-Sahd In the rat, a new structural sex difference of the nervous system was found: the density of axodendritic synapses (ADS) is larger in the male central component of the medial preoptic nucleus (MPNc), as proven by quantitative electron microscopy. The study included 24 animals...

...-antiperoxidase (PAP) and for VP with 5- or 15-nm gold. Many of the GnRH-IR and more than half the VP-IR cell bodies in the SON were NEU. VP-IR elements formed axodendritic and axosomatic symmetrical synapses with one another. In addition, VP-IR boutons also synapsed with NEU GnRH-IR neurons. Although GnRH axon...

... of autonomic function. The current ultrastructural immunocytochemical study was designed to examine the range of synaptic relationships that CRF terminals make within the PVN. CRF-positive synapses were numerous, particularly in the periventricular zone. The majority of terminals formed axo-dendritic synapses...
