Anatomical terms of neuroanatomy

The interposed nucleus is the combined paired globose and emboliform nuclei, (deep cerebellar nuclei) on either side of the cerebellum.[1][2] It is located in the roof of the fourth ventricle, lateral to the fastigial nucleus. The emboliform nucleus is the anterior interposed nucleus, and the globose nucleus is the posterior interposed nucleus.[3]

The interposed nucleus is responsible for coordinating agonist/antagonist muscle pairs, and therefore a lesion in this area causes tremor.
