The Conductive Scaffold for Spinal Cord Regeneration Bridge (CSRB) proposes simultaneous addressing of five fundamental barriers to CNS regeneration in a single implant: (1) CSPG chemical barrier, (2) myelin-associated inhibitory signaling, (3) lack of aligned physical substrate, (4) axon misrouting without topographic cues, and (5) demyelination of regenerated axons. This review synthesizes existing peer-reviewed literature to demonstrate that every functional element of the CSRB design has empirical support at the component level, and that partial combinations have already shown synergistic effects in vivo. The remaining experimental gap — simultaneous integration of all five components — is empirically narrow. This paper incorporates a dual-mode adversarial review (Miki-kun critique x ChatGPT reinforcement) as Section 10.
