Eye-hand reaching movements are controlled by a fronto-parietal network with distinct foci for the different functional subcomponents

Introduction: Reaching movements are combined of different subcomponents consisting of eye-hand movements towards a spatially located target. Within a parieto-premotor network specialized cortical areas seem to subserve differenzial functions concerning the control of the motor effector and the position in space. Besides the identification of commonalities, we also wanted to study the differenzial contribution of specialized areas that included frontal and parietal areas. Tasks consisted of various performances of saccades, reaching movements, and additionally covert shifts of attention towards a target presente…
