The brain organization for movement in a 20-year-old man with a history of intrauterine or perinatal right middle cerebral artery stroke was studied. [15O]-water positron emission tomography demonstrated a normal pattern of activation during finger movement in the right hand. Movement of the hemiparetic left hand was associated with activation in the supplementary motor area bilaterally and in the left premotor cortex. Blood flow increase was observed in the right temporal lobe adjacent to an extensive area of encephalomalacia, suggesting atypical motor function in the temporal lobe.
