| Research Abstract |
Prism adaptation technique with a few ways of target presentation was carried out in normals to clarify which condition is the most promising. Based on this result, three different ways of target presentation was adopted for prism adaptation in patients with left unilateral spatial neglect. Amelioration of left unilateral spatial neglect by prism adaptation was evaluated with line copying task, which was newly developed. As prism adaptation effect was positive in every target condition, it was not possible to tell that which is the best for neglect patients. In addition, finding behavioral and anatomical differences between patients with the positive effect and those with the negative effect, the results of paper and pencil tasks and lesion site were analyzed, respectively. These analyses, however, could not detect any differences between them.
