Kisspeptin neurons and the circuits that control ovulation
In females, the mid-cycle surge in gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH) secretion triggers ovulation. This neuroendocrine process is mediated by a population of neurons in the preoptic area that produce the neuropeptide kisspeptin and drive the activity of GnRH neurons for the surge. In female rodents, and possibly in other species, the preovulatory surge is timed to precede the onset of activity to ensure that ovulation coincides with sexual behavior. In this presentation, I will focus on the regulation of preoptic area kisspeptin neuron activity by the central circadian clock.
