Evidence for CNS control of the ante- rior pituitary has been derived from the experimental alteration of pituitary se- cretion by environmental factors, electri- cal stimulation of the CNS, pituitary stalk transection, and transplantation of the pituitary away from the CNS. CNS control of the pituitary is by way of the vascular link between hypothalamus and pituitary, the hypothalamo-hypophysial portal system. An area of the medial basal hypothalamus appears to synthe- size neurohormones regulating pituitary secretion and has been designated the hypophysiotrophic area. This area re- ceives neural inputs from other CNS areas and translates them into neuro- hormonal signals to the pituitary. A ma- jority of the concepts have been devel- oped from studies of the laboratory rat, but enough species differences exist in the control of ovulation to suggest that comparative studies would add greatly to our knowledge. The feedback of ovarian hormones as well as pituitary hormones on the CNS structures controlling the pituitary-ovar- ian axis has been verified in several ex- perimental situations. The exact sites of feedback action have been investigated by local implantation of hormones and by autoradiographic localization of radioac- tive hormones. Electrophysiological cor- relates of pituitary and ovarian hormone administration have also been recorded from CNS areas of varying sizes. |
