Here's a tidbit I found. Experiments in using nanotubes with neurons.

EETimes Story

It seems more a cerebral booster to me; lets hope it turns out something good.

... or the starting building blocks of neural cyberware.

Well, maybe the phisical interface betwen brain and machine, but brain can't be programmed to decode so we must learn how to make machine speak its lenguage (yes I know in some japanese university they were able to recreate what people see by scanning their brain, it's just the beginning we are still far from understanding how brain works).

Probably we will have to wait a generation or two before being able to see neural interfaces.

Not cyberware. It seems, in many area's, we are skipping cybernetics & bio-augmentation entirely in favor of nanotechnologies & genetics.

Nanocar

Looks like the beginning of neurointerface tech for cyberlimbs and possibly something along the lines of primitive ASIST technology.

Nanotech is required to make the wiring for the man-machine DNI interfaces. You can't have full blown cybernetics without the nanotech first unless you want the user to carry around a lot of external wiring and sensors.

It's also interesting the cellular trasistor link in the article linked in the OP, if a such thing could be built at cellular level to nonitor (and mabe stimulate) single neurones without harming them it could provide the input output interface to the brain.
