視覚運動変換の学習に伴う誤差と制御の動的秩序形成

抄録

Adaptation, learning and plasticity of visuomotor transformation are a neural strategy to update and enhance an internal process for the new environment. This study presents the formation, collapse, and reformation of patterns in the error-action relation in the error phase space during nine days of visuomotor learning that involves a participant who performs manual tracking in a heuristic trial-and-error way under reversed/unreversed vision. The analysis results show the geometrical features of dynamic structure in the error phase space reflect the level of individual ability and performance, suggesting the potential for quantitative evaluation of motor planning.
