Altered stepping: Averages of 10 steps (contralateral forelimb paw height) before (dashed lines and open triangles) and after CNQX (solid lines and solid circles) injections. SDs for each tenth of the swing phase are shown with vertical bars. A, rDAO inactivation produced lowered paw height in early swing with a midswing drag (2-32). B, rMAO inactivation produced severe height reduction and drag throughout the swing (7-23, limp case). C, D, With wall support, neither DMCC (5-22) nor cMAO (4-16) inactivation produced changes in the step cycle. E, β inactivation resulted in shorter steps with less midswing dip (2-16).
