BRAIN-CONTROLLED PROSTHETICS IN FUTUREFeb 12, 2005 - FreeMarketNews.comby Michael J. RossResearchers are making tremendous progress in developing artificial limbs that can be controlled by the brain activity of people wearing those limbs. These devices utilize what is known as a "brain-computer interface" (BCI), of which there are two varieties: An individual's neuronal activity measurements can be detected using "single-unit recording", in which each electrode is implanted adjacent to an individual brain cell. Alternatively, the brain activity can be measured using electroencephalography (EEG), in which electrodes are attached to the patient's scalp, to measure aggregate signals. It is expected that within...
