Microstructure of brain tissue under light microscope with 200 × magnification. (a–e) Microstructure of normal brain tissue, brain tissue at 2, 6, 10, and 24 hours after the onset of ischemic brain injury, respectively. The black circles denote the morphologic changes of brain tissue within the same area (the circles are in the same size).
