Surgery of tumors of the cerebellum and prefrontal cortex, and sensory memory and motor planning disturbances in children

This study addressed the integration of sensory short-term memory (SSTM) and motor planning (MP) in the lateral cerebellar region, where the dentate nucleus is localized, and in the prefrontal cortex (PF). Boucher and Lewis's test of SSTM and MP was administered pre- and postsurgically to 8 pat...

Description
Summary:This study addressed the integration of sensory short-term memory (SSTM) and motor planning (MP) in the lateral cerebellar region, where the dentate nucleus is localized, and in the prefrontal cortex (PF). Boucher and Lewis's test of SSTM and MP was administered pre- and postsurgically to 8 patients of either sex, between 5 and 19 years of age, with tumors of the cerebellum, PF (area 9 medial) or the parieto-occipital region, and on one occasion to 8 corresponding controls. Whereas lesions of the midline portions of the cerebellum and of the parietal-occipital region did not appear to cause any cognitive defects, patients with lesions affecting either the lateral cerebellar region or PF exhibited statistically significant deficits of SSTM and MP. The lateral cerebellum seems to act in concert with PF to integrate different cognitive activities related to holding objects in SSTM and planning motor strategies in reference to them.
