The hypothalamus, which is situated between the pituitary gland and the thalamus, is the part of the brain involved in appetite control and, more specifically, the arcuate nucleus within the hypothalamus. The arcuate nucleus, according to the most recent studies, is the brain’s control center with respect to appetite. It is this part of the brain that monitors and regulates insulin levels in the body.
While the hypothalamus is the part of the brain that receives signals indicating food intake is desired, the latest scientific research on appetite control has pointed to the discovery of a protein that apparently plays a major role in sending those aforementioned signals to the hypothalamus. Designated Gpr17, this newly discovered protein may provide medical researchers with the clue they have been seeking to better understand obesity. Having isolated and identified this protein, it should now be possible to develop medications that target it, rather than focusing on the broader issue of the hypothalamus, in which Gpr17 is active. In other words, this discovery will provide for more surgical or narrowly-defined targets for whatever pharmaceutical innovations are achieved in the years to come.
All of that information aside, however, the logical answer to the question “what part of the brain is responsible for appetite control” would be the hypothalamus.
