Fig. 3. Rats (n = 15 per group) were subjected to 50 min of middle cerebral artery occlusion while anesthetized with isoflurane or “awake” and allowed to recover for 8 weeks. Both neurologic deficit ( P = 0.05) and total infarct size ( P = 0.03) were reduced in the isoflurane group. Open circles indicate values for individual animals. Horizontal bars indicate group median values for neurologic scores and mean values for infarct volumes.
