Detailed explanation-1: -Optic ataxia is the inability to accurately point to or reach for objects under visual guidance with intact ability when directed by sound or touch despite normal strength. Therefore, a patient who can see an object may be unable to reach for it accurately until they physically contact it.
Detailed explanation-2: -This neurological deficit called optic ataxia is observed after damage to the dorsal stream.
Detailed explanation-3: -Optic ataxia is the impaired reaching for objects under visual guidance. It may be related to an older term for visual disorientation, the inability to localize the spatial position and distance of objects, resulting in problems scanning the environment, walking around obstacles, and reaching for objects.
