Stroke and spinal cord injuries can severely impair motor functions, and understanding how to promote recovery is a critical challenge. While damaged neurons in the brain and spinal cord have limited ability to regenerate, the brain can form or strengthen alternative neural pathways involving uninjured parts of the brain, enabling functional recovery. Such reorganization of pathways in the brain is called neural plasticity, and identifying the involved pathways and understanding their functions can aid researchers in developing more effective rehabilitation strategies.
