Question

Quizplus · Accepted Answer

In split-brain patients, the left hemisphere controls the right side of the body and vice versa. Therefore, when a complex command is presented to the right-ear patient, the information is sent to the left hemisphere, which is responsible for language processing, and the patient should comprehend it. Conversely, when the same command is presented to the left-ear patient, the information is sent to the right hemisphere, which is not responsible for language processing, and the patient may not comprehend it. Therefore, option B is correct, while options A, C and D are incorrect.
