The emboliform and globose nuclei, or interposed nuclei, have a similar course as the axons from the dentate, but with the addition of another synaptic target. Axons from the interposed nuclei decussate in the superior cerebellar peduncle to synapse on the contralateral ventral nucleus of the thalamus and the contralateral red nucleus in the midbrain (eFig. 9.70). Axons leaving the red nucleus descend to the inferior olivary nucleus in the medulla. The axonal projections from the interposed nuclei function in monitoring and correcting motor activity of the upper and lower extremities.
