- Abstract
[Purpose] The purpose of this study was to investigate the effects of task practice by one hand using the Go/NoGo visuomotor task on the contralateral hand. [Subjects] Subjects were 16 healthy persons who were right-handed. [Methods] Subjects were divided into 2 groups: the right-hand and left-hand practice groups. The Go/NoGo task consists of a light stimulus of 3 types. Subjects were required to extend the finger of one hand in response to presentation of a red circle (Go stimulus) and to keep at rest without exercise in response to presentation of a green circle or red square (NoGo stimulus). We measured the reaction times of both hands before and after 3 days of task practice. [Results] Shortening of the pre-motor time of the practice and no-practice hands occured in both practice groups. [Conclusion] These results suggest that 3 days of task practice causes a plastic change in the function of the posterior parietal cortex (PPC), while processed visual information was transmitted through the corpus callosum to the posterior parietal cortex on the same side as the finger movement.
