We measured the capacity of monkeys to project the arm to visually located targets under conditions differing in the nature of visual control allowed during reaching. This capacity was impaired by a unilateral posterior parietal lesion which increased the magnitude and variability of errors in projecting the contralateral arm to targets located on either side of the midline. Furthermore, accurate projections of the arm were often accompanied by misorientations of the fingers of the hand. These… CONTINUE READING
