Abstract

This commentary concerns the cerebellar contribution to cognition. It addresses the relevant historical background, elaborates upon the associative and paralimbic incorporation into both feedforward and feedback limbs of the cerebrocerebellar system, and relates this to the newly described cerebellar cognitive-affective syndrome. It then addresses the degree to which available anatomic data support current theories regarding nonmotor learning in the cerebellum, [HOUK et al.; THACH]
