Resumo(s)
Sexual behavior is one of the most important actions an individual will participate in during its lifetime. Although the general brain circuitry involved in the regulation of socio-sexual behaviors was identified almost 50 years ago, there are many still many open questions regarding the nature of these structures’ activities, how hormones affect them, and how they communicate with one another to control this fundamental behavior. In most female species, lordosis is the primary behavior displayed during copulation. During lordosis, the female arches her back upward in dorsiflexion and stays immobile to allow for penile insertion from her male partner. The periaqueductal gray (PAG) has been implicated as one of the primary brain areas involved with the
regulation of this sexual behavior, however until recently almost all of the research carried out in this brain area was done in the rat.
