摘要: Olfactory information is known to influence both male and female sexual behavior. Chemosensory compounds as pheromones activate distinct brain pathways, inducing innate stereotyped behaviors, well hormonal changes. Studies have shown that odors induce Fos expression in various nuclei of conspecific males, including the ventral premammillary nucleus (PMV). Although poorly investigated, previous studies suggested PMV plays a role aggressive In this study, we used protein marker for neurons responsive inexperienced rats exposed soiled bedding. We observed induced intense immunoreactivity throughout PMV. Most these also express cocaine- amphetamine-regulated transcript (CART) immunoreactivity. addition, situ hybridization that, following exposure odors, CART mRNA increased only Our results suggest stimulate production males. Considering leptin receptor, fact they project areas related reproduction, hypothesize integrate nutritional environmental (olfactory) information, being apt modulate reproductive
