A-C, Representative images of MBP (green) and SMI32 (red) immunostaining in the external capsule (EC, A), cortex (CTX, B) and striatum (STR, C). Scale bar = 50 μm. D, The relative ratio of SMI32 vs MBP immunostaining intensity in the ipsilateral hemisphere was expressed as a function of contralateral values, and expressed as mean ± SEM. N=5-7 per group. *P ≤ 0.05, *** P ≤ 0.001 vs sham, # P ≤ 0.05, ## P ≤ 0.01 vs vehicle.
