Brain interconnect already approaches the landauer limit for irreversible signalling, so changing out materials makes no difference unless you can also shrink the volume to reduce lengths, but as discussed in the section on density & temperature, the brain is also density bound based on the limits of heat transfer to the surface of the skin as a radiator.
