Task: Text Categorization
Input (English): Part of this structure is absent in a syndrome that can cause mega cisterna magna, and which is named for Dandy and Walker. This structure contains the fastigial, globose, emboliform, and dentate nuclei, which are collectively called its namesake "deep nuclei" and are located in the arbor vitae. Marr and Albus proposed theories of this structure's function. This structure includes a narrow medial tissue called its namesake vermis. Inputs in this structure diverge to stimulate a huge number of namesake granule cells, then converge to stimulate a much smaller number of Purkinje cells, which are among the largest neurons. For 10 points, name this portion of the brain involved in balance and motor skills, which is located under the cerebrum.
Output (English): Science
