title: Optic ataxia in Bálint-Holmes syndrome.
abstract: The objective of this review is to reinstate the diversity of visual perception and visuomotor symptoms following lesions to the posterior parietal cortex (dorsal visual stream). This diversity was overshadowed for a long time and shows the contribution of the dorsal visual stream not only to action but also to perception. More precisely, we propose that the visuomotor deficit in optic ataxia stems from two distinct components: visual proprioceptive deficit (hand effect) and visual attentional deficit (field effect) also affecting the perception in peripheral vision.
