If a split brain patient is shown an image of a spoon in their left visual field (using Sperry's apparatus), what would the patient be able to do to show they had seen the picture?

Question

Quizplus · Accepted Answer

The left visual field is processed by the right hemisphere of the brain. In split-brain patients, where the corpus callosum is severed, there is no communication between the two hemispheres. The right hemisphere controls the left side of the body but does not have direct access to language centers, which are typically located in the left hemisphere. Therefore, the patient would not be able to verbally identify the spoon but could demonstrate recognition by picking up a spoon with their left hand, which is controlled by the right hemisphere.
