FIGURE 3 | Restoration of function after spinal cord injury might arise from anatomical plasticity of damaged or spared connections.

a | Collateral sprouts (illustrated in red) might form from long descending pathways that bypass the lesion site and activate spinal circuits more effectively or activate novel circuits, or from damaged or intact descending projections that activate local propriospinal neurons that bypass the injury site and form a novel descending system. b | Ascending sensory projections might also form collateral sprouts, which activate spinal circuits more effectively.
