The hypothalamus is most often associated with innate behaviors such as is
hunger, thirst and sex. While the expression of these behaviors important for
survival of the individual or the species is nested within the hypothalamus, the
desire (i.e., motivation) for them is centered within the mesolimbic reward
circuitry. In this review, we will use female sexual behavior as a model to
examine the interaction of these circuits. We will examine the evidence for a
hypothalamic circuit that regulates consummatory aspects of reproductive
behavior, i.e., lordosis behavior, a measure of sexual receptivity that involves
estradiol membrane-initiated signaling in the arcuate nucleus (ARH), activating
?-endorphin projections to the medial preoptic nucleus (MPN), which in turn
modulate ventromedial hypothalamic nucleus (VMH) activity-the common output from
the hypothalamus. Estradiol modulates not only a series of neuropeptides,
transmitters and receptors but induces dendritic spines that are for estrogenic
induction of lordosis behavior. Simultaneously, in the nucleus accumbens of the
mesolimbic system, the mating experience produces long term changes in dopamine
signaling and structure. Sexual experience sensitizes the response of nucleus
accumbens neurons to dopamine signaling through the induction of a long lasting
early immediate gene. While estrogen alone increases spines in the ARH, sexual
experience increases dendritic spine density in the nucleus accumbens. These two
circuits appear to converge onto the medial preoptic area where there is a
reciprocal influence of motivational circuits on consummatory behavior and vice
versa. While it has not been formally demonstrated in the human, such circuitry
is generally highly conserved and thus, understanding the anatomy, neurochemistry
and physiology can provide useful insight into the motivation for sexual behavior
and other innate behaviors in humans.
