Research output: Contribution to journalReview articlepeer-review


Optic ataxia is an impairment of visually guided reaching that is attributable neither to primary visual, primary proprioceptive or motor deficits, nor to cerebellar or cognitive impairments. It is one of the triad of symptoms that make up Bálint’s syndrome, though it can be observed without the full syndrome following either bilateral or unilateral stroke, progressive degeneration or seizure, usually involving the posterior parietal cortex.
