The supramammillary nucleus is a small region located in the hypothalamus of the brain. It is situated above the mammillary bodies and plays a crucial role in various neurophysiological processes.

Structure[edit]

The supramammillary nucleus is part of the limbic system, which is involved in emotion, behavior, and memory. It is located dorsally to the mammillary bodies and is connected to several other brain regions, including the hippocampus and the thalamus.

Function[edit]

The supramammillary nucleus is involved in the regulation of arousal, sleep-wake cycle, and motivation. It has been shown to influence theta rhythm in the hippocampus, which is important for learning and memory processes.

Connections[edit]

The supramammillary nucleus has extensive connections with other parts of the brain. It projects to the hippocampus, septal area, and ventral tegmental area. These connections suggest its involvement in reward and motivational pathways.

Clinical significance[edit]

Dysfunction of the supramammillary nucleus may be associated with sleep disorders, mood disorders, and cognitive impairments. Research is ongoing to better understand its role in these conditions.

Research[edit]

Studies have shown that the supramammillary nucleus is involved in the modulation of dopaminergic activity, which is crucial for reward processing and addiction. Further research is needed to explore its potential as a target for therapeutic interventions.

-The supramammillary nucleus is a small, elongated structure located in the posterior hypothalamus. It is situated near the mammillary bodies, which are two small round bodies located on the undersurface of the brain. The supramammillary nucleus is composed of two main parts: the lateral and the medial parts. The lateral part is larger and more elongated, while the medial part is smaller and rounder.
