Representative images of cerebral intravital microscopy and microcirculation analysis of the cerebral cortex. The values represent the mean ± S.E.M (n = 6–8 per group). Bar graphs represent a the functional capillary density, and b the number of rolling leukocytes in venules after 12 weeks of physical exercise or sedentarism. Sham-Sed, sham surgery non-exercised group; Sham-Ex, sham surgery exercised group; 2VO-Sed, chronic cerebral hypoperfusion non-exercised group; 2VO-Ex, chronic cerebral hypoperfusion exercised group. In a *p < 0.05 vs. Sham-Sed and ^##p < 0.01 vs. 2VO-Sed (unpaired Student’s t test); in b **p < 0.01 vs. Sham-Sed and ^#p < 0.05 vs. 2VO-Sed (ANOVA). Scale bar 100μm, magnification100X in a and 200X in b
