Red Nucleus

The red nucleus is a massive cluster of neurons that form a neurological structure in the dorsal portion of the midbrain. It has an elongated form and a reddish gray hue. The red nucleus functions like a relay station, receiving afferent axonal fibers from the cerebellum contralateral half and also from the ipsilateral cerebral motor cortex ("Ipsilateral" means from the same side); it projects efferent fibers to the contralateral half of the reticular formation and spindal cord.
