The nucleus interpositus is a nuclear region in the Cerebellum, which consists of two parts.
Anatomy
The posterior nucleus interpositus corresponds to the Nucleus globosus, while the anterior nucleus interpositus corresponds to the Nucleus emboliformis. The nucleus interpositus is located in the roof of the fourth ventricle.
Afferents
The nucleus interpositus receives afferents from the anterior lobe of the cerebellum.
Efferents
The efferents of the nucleus interpositus travel via the Superior cerebellar peduncle to the Red nucleus.
