The Ventromedial Nucleus (VMN) is a part of the hypothalamus that is involved in a variety of functions, including appetite, weight regulation, and emotional responses. The VMN is located in the ventral part of the hypothalamus, and it is made up of a group of neurons that are interconnected with each other.
The VMN was first described by Viktor von Ebner in 1898. He called it the “nucleus ventromedialis hypothalami”. The VMN was further studied by Geoffrey Harris in the 1950s. He discovered that the VMN is involved in appetite and weight regulation.
an region of the hypothalamus inside the brain which is recipient to incoming data from the amygdala and is associated especially with ingesting food and carnal acts. It has normally been referenced as the satiety core due to its assumed dominance over the discontinuation of ingesting food ,but it is now realized that other neural regions are engaged in this operation too.
The VMN is a small, oval-shaped structure that is located in the ventral part of the hypothalamus. It is about 1 cm long and 0.5 cm wide. The VMN is made up of a group of neurons that are interconnected with each other. The VMN is connected to the amygdala, the hippocampus, and the prefrontal cortex.
The VMN is involved in a variety of functions, including:
- Appetite and weight regulation
- Emotional responses
- Sexual behavior
- Learning and memory
- Stress response
- Body temperature regulation
The VMN is a complex structure that is involved in a variety of important functions. It is still not fully understood, but it is an important part of the brain.

- Hypothalamus: The hypothalamus is a small, pea-sized structure that is located at the base of the brain. It is involved in a variety of important functions, including appetite, weight regulation, body temperature regulation, and the release of hormones.
- Amygdala: The amygdala is a small, almond-shaped structure that is located in the temporal lobe of the brain. It is involved in emotions, such as fear and anger.
- Hippocampus: The hippocampus is a seahorse-shaped structure that is located in the medial temporal lobe of the brain. It is involved in memory formation and consolidation.
- Prefrontal cortex: The prefrontal cortex is the part of the brain that is located at the front of the frontal lobe. It is involved in higher-order cognitive functions, such as planning, decision-making, and social behavior.
