Fig. 2. Coronal sections (bregma + 0.70 mm) were analyzed for presence of infarcted tissue in sectors of the neocortex and subcortex. All rats subjected to 50 min of middle cerebral artery occlusion in experiment 1 underwent this analysis. Values presented indicate the fraction of the total group (n = 15 per condition) in which infarct was evident in the respective sectors. A marked reduction in the incidence of infarct was present throughout the hemisphere ipsilateral to middle cerebral artery occlusion.
