Figure 6.

S1 corticospinal terminal labeling in segments C1–T2 of a control animal (left) and following DRL/DCL (right). Terminal areas are outlined in either red (control) or blue (DRL/DCL) and the lesion is always shown on the left side of the cord (gray shading). Note that there is no label contralateral to injections so S1 CST fibers do not cross the midline either in the healthy state or after injury. Inset graphs show distribution profiles for the individuals shown. The lines are smoothed using a quadratic weighted traveling mean. Gray lines indicate the location of the DCL in the lesioned animal or the relative cord position in the control.
