A specialized brain region of the ventral diencephalon arising near the end of the segmentation period; the embryonic hypothalamic region will give rise to the posterior pituitary gland as well as a number of brain nuclei. [ZFA]. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis).[Wikipedia].

homology notes
  • For instance, the vertebrate ventral diencephalon generates the hypothalamus which functions as a major endocrine center in cooperation with the hypophysis, the anterior part of the pituitary gland, located just ventral to the hypothalamus. In the amphioxus brain, the presence of a hypothalamus-like structure has been reported associated with the ventrally located Hatschek's pit, the hypothetical hypophysial homologue. It is thus conceivable that a hypothalamus-like structure originally involved in endocrine functions may have already been present before the establishment of vertebrates.[well established][VHOG]
