OPN promotes motor function recovery. A. Steps of the motor behavior testing process after stroke and injection of rOPN. B. Statistical analysis of the percentage of foot faults in the grid-walking test for stroke+saline and stroke+rOPN groups (number of mouse steps with errors = number of empty grids/total number of grids walked). C. Cylinder tests for stroke+saline and stroke+rOPN groups to assess the symmetry of forelimb movement. Data are expressed as the mean ± SEM, **P<0.01 vs. stroke+saline group. n=6 per group.
