What this Trial Is About
To produce hand's movement directed towards a target, the investigator must combine several sensory information, such as vision or proprioception. The posterior parietal cortex (PPC) is a region of the cortex involved in this multisensory integration. A lesion of the PPC cause a visuo-motor trouble called optic ataxia but these patients also have perceptual troubles. The aim of the study is to understand the different functions of the PPC and especially how the processes of spatial coding of the sensory information influences perception and motor planning. In this study, the investigator want to explore the sensory motor and the perceptual performance of patients with optic ataxia compared with healthy subjects, using 6 behavioral tests. Objectify the consequences of PPC impairment (visual-motor and perceptual consequences) on patients' quality of life and autonomy.
