Outline of Final Research Achievements

We can perform several physical activities with higher accuracy, even there are many kinds of internal and/or external fluctuation. This would imply that our motor system is equipped with some mechanism for compensating the internal and external perturbations automatically. However, it is still unclear that a contribution of visual motion information to adjustment of arm reaching. In the last decade, several visuomotor studies demonstrated that a visual background motion during target reaching induce a reflexive manual response. This response, which called manual following response (MFR), is reflexively evoked with very short latency. In this study, we have examined whether or not MFR are modulated to adjust according to environmental condition. In the result, MFR was implicitly modulated only under effectual condition. Thus, MFR modulator could be independent of processing of explicit visuomotor system.
