The red nucleus is a rounded structure located in the mesencephalon (midbrain) that plays a crucial role in motor coordination. It is involved in the regulation of voluntary movements and is particularly important for the control of limb movements. The red nucleus receives input from the cerebellum and the motor cortex and sends projections to the spinal cord, influencing muscle tone and movement through its connections with the rubrospinal tract. Its distinctive reddish color is due to high iron content and vascularization.
