Webb19 jan. 2024 · Neurons in the dorsomedial hypothalamus that express TrkB (DMH TrkB) have been implicated in the regulation of appetite; however, their relevance to energy expenditure is less clear.This study reveals that activation of DMH TrkB neurons potently induce thermogenesis and locomotor activity. Notably, increased energy expenditure … Webb27 maj 2024 · The hypothalamus is made up of three units. Anterior (supraoptic) nuclei These comprise the preoptic, medial and lateral areas. There are numerous distinct nuclei within this area, the details of which are beyond the scope of this article. Together, they are involved in a variety of functions including thermoregulation and hormone regulation.
