Answer:
In a split-brain procedure, the connection between the left and right hemispheres of the brain is severed. Typically, this is done to treat severe epilepsy when medication fails to control seizures. After the procedure, each hemisphere functions somewhat independently, with limited communication between them.
Now, if a patient who has undergone a split-brain procedure sits in front of a computer screen and focuses on a center point, here are a few possible scenarios to consider:
Visual Input: The computer screen may present visual stimuli to the patient, such as images or words. In a split-brain patient, the information presented on the left side of the screen would be processed primarily by the right hemisphere, while information on the right side of the screen would be processed primarily by the left hemisphere.
Motor Response: Depending on the task or instructions given to the patient, they may be required to respond in some way. For example, they might have to press buttons or type on a keyboard to indicate their responses. Motor responses are typically controlled by the contralateral hemisphere, meaning the left hemisphere controls the right side of the body, and vice versa.
Communication between Hemispheres: In a split-brain patient, communication between the left and right hemispheres is limited or non-existent. This means that information presented exclusively to one hemisphere may not be accessible to the other hemisphere. The patient may have difficulty verbally describing or conveying information that was presented to the hemisphere opposite to their language-dominant side (typically the left hemisphere for most individuals).
