Figure 4

Excitotoxic ablation of T8–T10 neurons abolishes the recovered control of stepping after a T12 lateral hemisection and after a T12 lateral hemisection followed by a delayed T7 lateral hemisection. (a,b) Survey and detail images of neighboring spinal cord sections (T8) stained for cresyl violet to show neurons (a) or luxol fast blue to show myelin (b) in uninjured mice or in mice after NMDA infusion (arrowheads). (c) Bar graphs showing the average maximum backward and forward angular positions of the limb axis depicted in Figure 1b during stepping 2–5 d after NMDA injection. Values represent means ± s.e.m. *P < 0.001, statistically significant difference compared to uninjured mice. Scale bars, 170 μm and 35 μm for survey and detail images, respectively.
