Title: Individuals with Cerebellar Degeneration Show Similar Adaptation Deficits with Large and Small 1 Visuomotor Errors. 2 3 4 5

31 32 The cerebellum has long been recognized to play an important role in motor adaptation. Individuals 33 with cerebellar ataxia exhibit impaired learning in visuomotor adaptation tasks such as prism 34 adaptation and force field learning. Both types of tasks involve the adjustment of an internal model in 35 order to compensate for an external perturbation. This updating process is error-driv...

Adaptation to visuomotor rotation and force field perturbation is correlated to different brain areas in patients with cerebellar degeneration.

Although it is widely agreed that the cerebellum is necessary for learning and consolidation of new motor tasks, it is not known whether adaptation to kinematic and dynamic errors is processed by the same cerebellar areas or whether different parts play a decisive role. We investigated arm movements in a visuomotor (VM) rotation and a force field (FF) perturbation task in 14 participants with c...

Dissociating the Roles of the Cerebellum and Motor Cortex During Adaptive Learning

Adaptation to a novel visuomotor transformation has revealed important principles regarding learning and memory. Computational and behavioral studies have suggested that acquisition and retention of a new visuomotor transformation are distinct processes. However, this dissociation has never been clearly shown. Here, participants made fast reaching movements while unexpectedly a 30-degree visuom...

Dissociating the roles of the cerebellum and motor cortex during adaptive learning: the motor cortex retains what the cerebellum learns.
