FIG. 5.

Motor mapping reflected structural damage of the spinal cord after contusive SCI. (A) Cross-sectional images of spinal cords at levels of lesion epicenter after different severities of spinal cord contusion. Dotted red lines outline the lesion areas. (B) Mean lesion areas at levels of epicenter after mild, moderate, and severe SCI. ***p < 0.001. Scale bar, 50 μm. (C) There is a negative correlation between motor map size at 6 weeks after SCI and the lesion areas of the injured spinal cord. SCI, spinal cord injury.
