Point 22. Red Nucleus (the "Ruber") The red nucleus is a prominent structure within the rostral midbrain and lies just dorsal to the substantia nigra. It appears to have a high iron content and is more vascular than the surrounding tissue, and in some brains is pinkish. Very little is known about the function(s) of the red nucleus in humans. Inputs to the ruber arise from motor areas of the brain and in particular the deep cerebellar nuclei (via superior cerebellar peduncle; crossed projection) and the motor cortex (corticorubral; ipsilateral projection).
