The ventromedial nucleus of the hypothalamus (VMN, VMH or ventromedial hypothalamus) is a nucleus of the hypothalamus. In 2007, Kurrasch et al. found that the ventromedial hypothalamus is a distinct morphological nucleus involved in terminating hunger, fear, thermoregulation, and sexual activity. [1]
These neurons, generated from the ventral part of the periventricular epithelium during embryonic development, locate dorsally in the hypothalamus, becoming part of the ventromedial hypothalamic region. [3] [2] [4] The function of the arcuate nucleus relies on its diversity of neurons, but its central role is involved in homeostasis. The ...
The hypothalamus, in particular, has been recognized as a key player in processing hunger signals and coordinating feeding behavior. [24] Advanced neuroimaging techniques have allowed researchers to map the brain circuits involved in hunger and satiety, revealing a complex network that integrates signals from the digestive system, adipose ...
The hypothalamus responds to these motivations by regulating activity in the endocrine system to release hormones to alter the behaviour of the animal. [5] These hormones include epinephrine (adrenaline) to increase blood flow and heart rate for a sufficient fight-or-flight response, [6] and ghrelin, which is commonly described as "the hunger ...
David Booth carried out work that contradicted the theory that dual centres of the hypothalamus control eating, the lateral hypothalamus for hunger [2] and the ventromedial hypothalamus for satiety [3] and began to replace it with a theory of the control of food choice and intake through learnt connections distributed around the brain.

Agouti-related protein is expressed primarily in the adrenal gland, subthalamic nucleus, and hypothalamus, with lower levels of expression in the testis, kidneys, and lungs. The appetite-stimulating effects of AgRP are inhibited by the hormone leptin and activated by the hormone ghrelin. Adipocytes secrete leptin in response to food intake.
The former CEO of Abercrombie & Fitch (A&F) has dementia and late onset Alzheimer's disease, his legal team has said in a court document filed in New York. Lawyers for Mike Jeffries have requested ...
