The median preoptic nucleus is located in the preoptic area of the hypothalamus.Forming a critical part of the anteroventral third ventricle and the midline of the lamina terminalis, the median preoptic nucleus occupies an anatomical position that allows it to play an important role in many aspects of homeostatic regulation.
The median preoptic nucleus is located along the midline in a position significantly dorsal to the other three preoptic nuclei, at least in the crab-eating macaque brain. It wraps around the top (dorsal), front, and bottom (ventral) surfaces of the anterior commissure. The median preoptic nucleus generates thirst.
The role of the SFO in angiotensin regulation is particularly important, as it is involved in communication with the nucleus medianus (also called the median preoptic nucleus). Some neurons in the SFO are osmoreceptors , being sensitive to the osmotic pressure of the blood.

The ventrolateral preoptic nucleus (VLPO), also known as the intermediate nucleus of the preoptic area (IPA), is a small cluster of neurons situated in the anterior hypothalamus, sitting just above and to the side of the optic chiasm in the brain of humans and other animals.
Outputs from the parabrachial nucleus originate from specific subnuclei and target forebrain sites involved in autonomic regulation, including the lateral hypothalamic area, ventromedial, dorsomedial, and arcuate hypothalamic nuclei, the median and lateral preoptic nuclei, the substantia innominate, the ventroposterior parvicellular and ...
The primary input regions to the lateral habenula (LHb) are the lateral preoptic area (bringing input from the hippocampus and lateral septum), the ventral pallidum (bringing input from the nucleus accumbens and mediodorsal nucleus of the thalamus), the lateral hypothalamus, the medial habenula, and the internal segment of the globus pallidus (bringing input from other basal ganglia structures).
