| Abstract(in English) | The spatial relationships among reaching objects and our body parts (arm, eye, head, etc) are quite important in producing arm movements. These relationships have been examined in many previous studies of voluntary movements from the view points of coordinate representation and those transformations, but it is still unclear how these relationships are represented and used in involuntary movements. To explore this issue, we examined the effects of the spatial relationships among gaze, reaching-target and background visual motion on the reflexive visuomotor response induced by a background visual motion, called Manual Following Response (MFR). The results showed that 1) the amplitude of the MFR monotonically decreased with the separation between gaze and reaching-target, and 2) the spatial relationship between reaching-target and background visual motion did not affect the MFR. Given these results, it is suggested that the spatial relationship between gaze and reaching-target modulates the reflexive visuomotor gain. We will explain this modulation by the gain field model of which maximum is obtained when gaze location is matched to the reaching target. |
