The ventromedial nucleus (sometimes referred to as the ventromedial hypothalamus) is a nucleus of the hypothalamus.
Division
It has four subdivisions:
- anterior (VMHa)
- dorsomedial (VMHdm)
- ventrolateral (VMHvl)
- central (VMHc).
These subdivisions differ anatomically, neurochemically, and behaviorally.
Function
The ventromedial nucleus is most commonly associated with satiety.
The VMHdm has a role in the male vocalizations and scent marking behaviors.[1][1][1]
The VMHvl plays a role in sexual behaviors in both the males and the females (lordosis in the females and mounting in the males.[1][1][1][1]
