This chapter reviews recent accounts on the nature of the well-established visuo-motor deficits in optic ataxia (OA) and presents original data revealing visuo-perceptual deficits in patients with OA. The research reviewed in this chapter challenges the long-held assumption that OA occurs independently from other perceptual or attentional deficits. The findings also demonstrate that research on OA requires a fundamental reappraisal both regarding the specificity of visuo-motor deficits and regarding the careful analysis of underlying lesions and disruptions to normal connectivity caused by those lesions, which would benefit from diffusion tensor imaging techniques.

Keywords:   optic ataxia, visuo-motor deficits, attentional deficits, perceptual deficits, diffusion
