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] This nuclear region is involved in the recognition of the feeling of fullness.
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 is located below the thalamus and is part of the limbic system. [1] It forms the basal part of the diencephalon. All vertebrate brains contain a hypothalamus. [2] In humans, it is about the size of an almond. [3] The hypothalamus has the function of regulating certain metabolic processes and other activities of the autonomic ...

The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain. The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear , as it is critical in the regulation of amygdala activity in humans.

The preoptic area is a region of the hypothalamus. MeSH classifies it as part of the anterior hypothalamus. TA lists four nuclei in this region, (medial, median, lateral, and periventricular).
Results of other studies showed that the neural hypophyseal stalk and ventromedial region of the hypothalamic arcuate nucleus receive arterial blood from ascending and descending infundibular branches and capillaries, coming from arteries of the superior hypophyseal arterial system. [3]
The hypothalamospinal tract is an unmyelinated [1] non-decussated [2] descending nerve tract that arises in the hypothalamus and projects to the brainstem and spinal cord to synapse with pre-ganglionic autonomic (both sympathetic and parasympathetic) neurons.
