Fig. 28. Abnormal handpaths in a subject with damage to the visual cortex are shown. The subject is viewed from above as he moves his head from a start position directly in front of him in the midline to targets located within arm's length to the left, right and straight ahead. Note the inaccuracy of movements with both hands (errors in excess of 5 cm) and movement curvature. Individuals without brain lesions make such movements in almost a straight line and nearly every movement terminates on target.
