Evaluation of infract size after photothrombotic stroke. (a) Representative immunohistochemical staining images of coronal sections in sham, stroke and stroke + stress. The infract area is identified with asterisks (*) and scale bar represents 0.1 cm. (b) Regional distribution of the percentage infarct areas in coronal sections aling the rostrocaudal axis as measured from bregma. The percentage infarcted areas are determined by the equation: [(area of contralateral hemisphere – area of ipsilateral hemisphere)/area of contralateral hemisphere] × 100%. The data are shown as the means ± SEM (n = 8 per group). *p < 0.05, ***p < 0.001 (one-way ANOVA followed by Tukey’s multiple comparisons).
