Quizplus · Accepted Answer

The right hemisphere of the brain is responsible for processing visual information from the left visual field, and the left hemisphere is responsible for processing visual information from the right visual field. Therefore, if an object is presented in such a way that only the right hemisphere receives the visual information, the patient will not be able to name the object because language processing occurs primarily in the left hemisphere. However, they will be able to point to the object with their right hand because the motor control for the right hand is controlled by the left hemisphere.
