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][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]
