At the level of the red nucleus, the output limbs of the pathways part company. Fibers of the cortical path(the one originating in the dentate nucleus) may relay in the parvocellular part of the red nucleus but for the most part continue on to terminate in the nucleus ventralis lateralis of the thalamus (see Slides 28 & 30). From there they project to the premotor area of the cortex (Area 6). Fibers of the spinal cord path (the ones originating in the globose and emboliform nuclei) terminate in the magnocellular part of the red nucleus ending upon cells that contribute axons to

the rubrospinal pathway. Thus, the rubrospinal path completes the spinal cord loop and is the route by which the intermediate part of the cerebellum can modify ongoing motor activity.
