After Joe has a stroke, his doctor asks Joe to touch his right pointer finger to his chin—but Joe is unable to move his right hand. However, when the doctor stimulates Joe’s pointer finger with a painful stimulus, Joe’s muscles quickly move his hand away from the stimulus. The doctor concludes that ______.

the stroke caused damage to Joe’s right primary motor cortex
the stroke caused damage to Joe’s left premotor cortex
