The red nucleus or nucleus ruber is a structure in the

extrapyramidal motor system
.

Function

In a

inferior olivary complex, an important relay center in the medulla.[1]

Input and output

The red nucleus receives many inputs from the cerebellum (interposed nucleus and the lateral cerebellar nucleus) of the opposite side and an input from the motor cortex of the same side.[10]

The red nucleus has two sets of efferents:[10]

  • In humans, the majority of the output goes to the bundle of fibers continues through the medial tegmental field toward the inferior olive of the same side, to form part of a pathway that ultimately influence the cerebellum.
  • The other output (the rubrospinal projection) goes to the
    primates
    , because of the well-developed cerebral cortex, the corticospinal tract has taken over the role of the rubrospinal.
