A person with epilepsy had a successful surgery to prevent the spread of epileptic activity between the two hemispheres of the brain. When an object is presented to the left visual fields of both eyes, this person can see the object but cannot verbally describe the object. When the object is presented to the right visual fields of both eyes, this person can see the object and is able to verbally describe the object. a. Describe the visual pathway from left visual fields to perception in the brain. b. Identify the area of the brain responsible for speech production. Include the name of the area, the lobe(s) and the hemisphere of the brain it is located in. c. Explain why there is a disconnect between vision and speech in the person described at the beginning of this question.
