The ventromedial nucleus (sometimes referred to as the ventromedial hypothalamus) is a nucleus of the hypothalamus.

DivisionEdit

It has four subdivisions:

• anterior (VMHa)
• dorsomedial (VMHdm)
• ventrolateral (VMHvl)
• central (VMHc).

These subdivisions differ anatomically, neurochemically, and behaviorally.

FunctionEdit

The ventromedial nucleus is most commonly associated with satiety.

The VMHdm has a role in the male vocalizations and scent marking behaviors.^[1][2][3]

The VMHvl plays a role in sexual behaviors in both the males and the females (lordosis in the females and mounting in the males.^[4][5][6][7]
