ABSTRACT
The olfactory accessory system is specialized in the detection of pheromones, being an afferent to medial extended amygdala. In spite of the fact that numerous phenotypes are found in these structures, in the current literature, there are no detailed descriptions about the phenotype of neurons in the vomeronasal systemmedial extended amygdale after their activation by pheromonal stimuli. Using immunohistochemistry for fos and dual immunohistochemistry for fos and phenotypes, here we show that females have a greater number of activated neurons by the pheromonal stimulus. Likewise, a great colocalization of fos with GABA, calretinin, and calbindin was observed in the vomeronasal systemmedial extended amygdala. These data suggest that in amygdaloid areas, neuronal excitability is controlled by GABAergic neurons that contain different calcium-binding proteins, indicating the important role of inhibitory control on the incoming sensory pheromonal and olfactory inputs controlled and processed by the vomeronasal system (AU)
