MOTOR ORGANIZATION AFTER EARLY MIDDLE CEREBRAL-ARTERY STROKE - A PET STUDY

The brain organization for movement in a 20-year-old man with a histor y of intrauterine or perinatal right middle cerebral artery stroke was studied. [O-15]-water positron emission tomography demonstrated a nor mal pattern of activation during finger movement in the right hand. Mo vement of the hemiparetic left hand was associated with activation in the supplementary motor area bilaterally and in the left premotor cort ex. Blood flow increase was observed in the right temporal lobe adjace nt to an extensive area of encephalomalacia, suggesting atypical motor function in the temporal lobe, (C) 1998 by Elsevier Science Inc.
