The interpositus nucleus projects to the contralateral red nucleus via the superior cerebellar peduncle. The ruber can then influence the contralateral spinal cord via the rubrospinal projection. Compared to the dentate, the interpositus influences the motor system more quickly. The interpositus also projects to cells in VA/VL, which in turn project directly to MI for any correction that is needed. The cells in VA/VL that project to PM and SMA receive input from the dentate, while those that project to MI receive their input from interpositus.
