Immunohistochemical analysis was performed to assess neurons (neurofilaments), astrocytes (glial fibrillary acidic protein), pericytes (α-smooth muscle actin), basement membrane (collagen IV), vessels (cluster of differentiation 34), and caveolae (caveolin-1). *P< 0.05 and **P< 0.01 vs all other regions; ^#P< 0.05 vs Cerebellum; ^&P< 0.05 vs Hippocampus; ^ICerebellar cortex; ^§Dentate nucleus; ^ƒAmmon’s horn layer 3; ^$Globus pallidus
