Deep Nuclei Intro Review Dentate Interpositus Fastigial Vestibular   Problems Contents Anatomy

Now we can take the information out of the deep cerebellar nuclei and the vestibular nuclei to where it can do some good, i.e., to the spinal cord, brain stem and thalamus. We already know a lot of this from our discussions of the Superior Cerebellar Peduncle (Point 18) and the Vestibular Nuclei (Point 13). The dentate nucleus projects primarily to the contralateral VA/VL nuclei of the thalamus via the superior cerebellar peduncle. Cells in VA/VL project to the premotor area (PM) and the supplementary motor area (SMA), both of which are motor "planning" areas. These cortical planning areas then project to primary motor cortex (MI or area 4) and from there the information is conveyed to the corticospinal system.
