Jody : C nano tubules : Cholesterol...

Cholesterol / fatty tissue laser shavings, migrated to the cranium could be succesfuly reconstructed into carbon nano tubules highways. Either inside the cellular matter or along the veins. There is a possible downside, that Dejavu could be experienced.
Another benefit could be the growth of Carbon nano-tubule super highways to replace spinal breaks. Repairing spinal column breaks with faster electro conductivity. Further constructs could be grown at the atomic level. Devices and networks capable of enhancing and cognitive/memory capacity. possibly external interfaces. wireless even, Honey.
