The OP's article does a lot more to disprove such a hypothesis by instead offering a more credible alternative explanation:
Neurons found in the CNS have tubles large enough to allow transport of ions and even relatively large polypeptides similar to, but more permissive than, the well-known gap junctions found between smooth muscle and cardiac muscle cells.
Penrose's hypothesis is crank science about quantum gravity messing with your CNS in a way comparable to "body thetans" in Scientology.
