Finally, we know that the superior cerebellar peduncle (brachium conjunctivum; Point 18) is the primary efferent (out of the cerebellum) peduncle of the cerebellum. It contains fibers that arise from several deep cerebellar nuclei. These fibers pass rostrally for a while (ipsilaterally) and then cross at the level of the inferior colliculus to form the decussation of the superior cerebellar peduncle. These fibers then continue rostrally to terminate in the red nucleus ("RUBER-DUBER") and the motor nuclei of the thalamus (VA, VL).
