Abstract:
:Characteristic increases in neuronal activity coincident with the pulsatile release of luteinizing hormone from the pituitary gland have been recorded from electrodes chronically implanted in the medial basal hypothalamus of the rhesus monkey. This electrophysiologic manifestation of the hypothalamic 'pulse generator' which governs the secretion of hypothalamic luteinizing hormone releasing hormone provides, for the first time, direct access to the central component of the neuroendocrine control system which regulates reproductive processes in this higher primate.
