A direct main olfactory bulb projection to the ‘vomeronasal’ amygdala in female mice selectively responds to volatile pheromones from males
The presence of a direct MOB‐to‐medial amygdala pathway in mice and other mammals could enable volatile, opposite‐sex pheromones to gain privileged access to diencephalic structures that control mate recognition and reproduction. Expand
Increased expression of c-fos in the medial preoptic area after mating in male rats: Role of afferent inputs from the medial amygdala and midbrain central tegmental field
The results suggest that olfactory inputs, possibly of vomeronasal origin, contribute to the activation of c-fos in the medial amygdala, and that afferent inputs from the central tegmental field and from the medial amy interact to promote cellular activity, and the resultant induction of c.fos, in the ipsilateral bed nucleus of the stria terminalis and medial preoptic area.

Olfactory Sex Discrimination Persists, Whereas the Preference for Urinary Odorants from Estrous Females Disappears in Male Mice after Vomeronasal Organ Removal
The results suggest that the VNO is not required for sex discrimination but instead detects the nonvolatile components of opposite-sex urine that may be used to help prolong contact with individuals that produce these chemosignals. Expand
Neuroendocrine Regulation of GnRH Release in Induced Ovulators
A complete understanding of the neuroendocrine control of ovulation will only be achieved by comparative studies of several animal model systems in which mating-induced as well as spontaneous, hormonally stimulated activation of GnRH neurons drives the preovulatory LH surge. Expand

Testicular androgen may cause behavioral defeminization only in those species in which expression of feminine sexual behavior normally depends on the neural action of progesterone, acting synergistically with estradiol; new data support this claim in the ferret. Expand
Vomeronasal neuroepithelium and forebrain Fos responses to male pheromones in male and female mice.
The results suggest that sexually dimorphic central responses to pheromones exist in mice that may begin in the VNO neuroepithelium and suggest that neurons in the central portions of the male's VNO pathway are capable of expressing Fos. Expand
Genetic and hormonal factors modulate spreading depression and transient hemiparesis in mouse models of familial hemiplegic migraine type 1.
It is shown that transgenic mice expressing R192Q or S218L FHM1 mutations have increased SD frequency and propagation speed; enhanced corticostriatal propagation; and, similar to the human F HM1 phenotype, more severe and prolonged post-SD neurological deficits. Expand
The main and the accessory olfactory systems interact in the control of mate recognition and sexual behavior
Recent results showing that both the main and accessory olfactory systems are able to process partially overlapping sets of sexual chemosignals and that both systems support complimentary aspects in mate recognition and in the control of sexual behavior are summarized. Expand
Sex comparison of neuronal fos immunoreactivity in the rat vomeronasal projection circuit after chemosensory stimulation
The results suggest that the previously established sexual dimorphism in the morphology of the rat's vomeronasal projection circuit is not reflected in the functional responsiveness of neurons in this circuit to chemosensory cues emitted by female conspecifics. Expand
Copulation in Castrated Male Rats following Combined Treatment with Estradiol and Dihydrotestosterone
Castrated male rats injected daily with 2 micrograms of estradiol benzoate (EB) combined with 200 micrograms of dihydrotestosterone propionate (DHTP) displayed masculine mating behavior which wasExpand
