Deep Brain Stimulation
Deep Brain Stimulation or DBS is a neuroprosthetic type. Currently DBS devices are in essence, a pacemaker for the brain. There is, however, no reason why they have to stay as simply that, and the term can easily open up to include any kind of implant deep into the brain for regulation or replacement of functions.

Powering a neuroprosthetic is a tricky issue. As most of these devices are implanted either on the surface of the brain, or deep inside its folds, it is not a trivial matter to pop it out and change the battery. But, what if the same sugar that feeds the brain, could also feed the prosthetic?
A look at one of Arthur C Clarke's quotes on training the brain to understand a new sense, and comparing that to actual experimentation with deep brain prosthetics.

Following an interesting attempt at using nanotech material to 'hide' a deep brain electrode array from the auto-immune system, and allow it to interface for far, far longer.

An interesting quote from the slightly obscure cyberpunk novel We can Build You, discussing details of a mood altering piano which does correspond well to what we know of the brain. Hook it up to a device which sends a different stimulation signal for every note played, and brain music takes on a whole new meaning.
Here we see a control room deep in a bunker complex. On one of the screens in front of the operator, a live video feed has just opened. What is perhaps unusual about the feed, is it is coming directly from someone's brain. A small monkey in a bio-jar, next to the woman it thinks of as its friend, family, loved one, has just noticed two decidedly unfriendly shapes surfacing out in the ocean, presumably having walked along the sea floor. Its eyes have focussed on them, and its brain processed the images.
