A neuroprosthetic is quite simply an artificial prosthetic device which interfaces with the central nervous system. A prosthetic either on the surface of, or buried deep inside the brain, in other words.

A look at the fundamental problems plaguing the development of neuroprosthetic devices.
A story about the state of tech at the end of 2006. Neuroprosthetic devices had some concrete success stories in the past few years, and the stage was finally set for developing them, not to just monitor and interact with brain signals, but control external body parts as well.
Discussion of a possible hardware-based neuroprosthetic interface method designed to maximise speed gain in body-machine sensory interfaces.
A new tack in neuroprosthetic interfaces is being born out of pulses of light rather than electricity. Termed 'optogenetic neuromodulation, the technique is being pioneered in the hope that it will enable a far greater level of accuracy and single-cell stimulation than is possible with electrode interfaces.
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?
IMEC, a nanotechnology company out of Leuven, Belgium, has developed a new approach to neuroprosthetics, an electrode probe that is capable of two-way data transfer. It can read neighbouring electrical impulses, and at the same time, transmit new impulses back.
It was long suspected but never proven that attaching a neuroprosthetic to the brain, was a valid way of providing therapy, and inspiring growth in the organ. Never proven until now, that is.
Optogenetics as a field of study, is only a few years old but already a means has been found to make use of it in living brains. Light-detecting proteins combined with gene therapy and an optical neuroprosthetic with a BrainGate style 3D array allow true two-way communication between the brain and a computer system.
NeuroPhone is exactly what it sounds like - a neuroprosthetic mobile phone. Developed by Tanzeem Choudhury, Rajeev Raizada and Andrew Campbell of Dartmouth College, New Hampshire, the phone makes use of an EEG helmet and the P300 response to make phone calls.
