Neural control of cyclic reproductive functions in the mammal

Abstract

A review of the neural control of cyclic reproductive functions in the mammal is presented. Methods in neuroendocrinology the hypothalamus and neural centers outside the hypothalamus are discussed. It is concluded that although the cortex the septal complex and the hippocampus register changes in electrical activity during cyclic events or after hormonal treatment in the female animal the changes do not necessarily indicate that such areas exert a direct control over cyclic reproductive activities. The amydala appear to have an important regulatory role in LH release and may constitute a site of sexual steroid feedback. During the reproductive cycle changes in the thalamus were evident but its role and that of the medial forebrain bundle are not clear. The midbrain reticular formation in the mesencephalon is affected by reproductive activities and may regulate the release of gonadotropins by the pituitary.
