Ipsidirectional impairment of prism adaptation after unilateral lesion of anterior cerebellum

Neurology. 2005 Jul 12;65(1):150-2. doi: 10.1212/01.wnl.0000167945.34177.5e.

Abstract

In a patient with damage of the left cerebellar cortex (SCA territory), the authors tested four combinations of exposure to optical shift (leftward prisms, right hand; rightward prisms, right hand; leftward prisms, left (ataxic) hand; rightward prisms, left (ataxic) hand). He adapted to rightward but not leftward prisms, independent of which hand was used during exposure. This suggests a role of anterior cerebellar cortex in the computation or compensation of ipsidirectional visual error.
