Question

Quizplus · Accepted Answer

Optic ataxia is a deficit that results specifically from damage to the "how" visual pathway, which is responsible for using visual information to guide one's own movements. It can lead to difficulties with visually guided movements, such as reaching for an object. Tritanopia is a form of color blindness affecting the blue-yellow spectrum, akinetopsia is the inability to perceive motion, and apoptosis is a type of cell death. None of these are directly related to difficulties with visually guided movements.
