Anatomical terms of neuroanatomy

The interposed nucleus is the combined globose and emboliform nuclei on either side.[1][2] The interposed nucleus is one of the paired cerebellar nuclei.[1] It is located in the roof (dorsal aspect) 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.
