Hormonal and chemosensory signals regulate social behaviors in a wide variety of
mammals. In the male Syrian hamster, these signals are integrated in nuclei of the medial …

Several developments during the past 15 years have profoundly affected our understanding
of the vomeronasal system (VNS) of vertebrates. In the mid 1990s, the vomeronasal …

Sexual behavior is directed by a sophisticated interplay between steroid hormone actions in
the brain that give rise to sexual arousability and experience with sexual reward that gives …

The medial preoptic area (MPOA), at the rostral end of the hypothalamus, is important for the
regulation of male sexual behavior. Results showing that male sexual behavior is impaired …

Previous work has shown that mating induces the expression of Fos protein within the
chemosensory pathways of the male Syrian hamster brain. 37 However, it is not known if this …

Comparative neuroanatomical investigations in primates and non-primates have helped
disentangle the anatomy of the basal forebrain region known as the substantia innominata …

In the present study a comparison was made between the distribution of Fos
immunoreactivity in the brain of female and male rats following successive elements of …

Induction of immediate-early genes (IEGs), such as c-fos, has been widely used to mark the
activation of brain regions following different types of sexual stimulation and behavior. A …

We recorded multiple unit neural activity [multiunit activity (MUA)] from inside and outside of
the suprachiasmatic nucleus (SCN) in freely moving male golden hamsters housed in …

Several studies have suggested dissociations between neural circuits underlying the
expression of appetitive (eg, courtship behavior) and consummatory components (ie …
