Brain Teaser: Split-Brain Patient
Question:
What would a split-brain patient be able to say if blindfolded and given a spoon in the right hand and a toothbrush in the left hand?Answer:
The split-brain patient would be able to say 'A) Spoon.'When a split-brain patient is blindfolded and given a spoon in the right hand and a toothbrush in the left hand, they would be able to verbally identify the spoon. This is because the sensory feedback from the right hand is processed by the left hemisphere of the brain, which houses the language centers.
Due to the intact connection between the right hand and the speech centers in the left hemisphere, the patient can say 'Spoon' but would not be able to name the toothbrush held in the left hand. This is because the information from the left hand is processed in the right hemisphere, which cannot communicate with the speech center in the left hemisphere due to the severed corpus callosum.
