dorsal hypothalamic area

[TA]
a relatively small region of the hypothalamus located inferior to the hypothalamic sulcus; contains the following nuclei: portions of the dorsomedial nucleus [TA] (nucleus dorsomedialis [TA]), endopeduncular nucleus [TA]) (nucleus endopeduncularis [TA]), and portions of the nucleus of the ansa lenticularis (nucleus ansae lenticularis [TA]).

The ventral part of the nucleus also sends fibers through the medial forebrain bundle to the medial preoptic and anterior hypothalamic areas, to the lateral hypothalamic area and the dorsomedial nucleus, to the mammillary body (including the supramammillary region), and the ventral tegmental area.
[19] In a subsequent study, [21] the same research team assessed a sample of patients with intractable OCD and found increased glucose metabolism in several brain regions: left cingulate gyrus, gray matter in the superior frontal gyrus, gray and white matter in the middle frontal gyrus, white matter in the inferior frontal gyrus, white matter outside the putamen, white matter in the anterior commissure of the limbic lobe, parahippocampal gyrus, dorsomedial nucleus of the thalamus, and amygdale.
We found that short-term morphine exposure down regulated and long-term morphine exposure up regulated rat hypothalamic P-CREB, PC1/3, and PC2 protein levels, and immunofluorescence studies confirmed these regulatory actions of morphine in the paraventricular and dorsomedial nucleus of the hypothalamus [40].
