For 10 points, name this gland located just above the brain stem that links the nervous and endocrine systems.
This structure contains the suprachiasmatic nucleus, which is responsible for the synchonization of slave oscillators and which receives direct input from the retina. Neurons of its arcuate nucleus terminate in the median eminance and are responsible for the release of dopamine into a certain (*) portal system. This structure is in part responsible for menstrual cycle regulation by releasing GnRH to stimulate FSH and LH release. Its paraventricular neurons control the release of oxytocin and vasopressin and project directly to the posterior pituitary.
