Brain-controlled interfaces are devices that capture brain transmissions involved in a subject's intention to act, with the potential to restore communication and movement to those who are immobilized. Current devices record electrical activity from the scalp, on the surface of the brain, and within the cerebral cortex. These signals are being translated to command signals driving prosthetic limbs and computer displays. Somatosensory feedback is being added to this control as generated

New technology to engineer the tissue-electrode interface, electrode design, and extraction algorithms to transform the recorded signal to movement will help translate exciting laboratory demonstrations to patient practice in the near future. From the rapid growth in biotechnology, neural engineering has emerged as a new field. The merger of systems neurophysiology and engineering has resulted in approaches to link brain activity with man-made devices to replace lost sensory and motor function. The excitement in this field is based not only on the prospect of helping a wide range of patients with neural disorders, but also on the certainty that this new technology will make it possible to gain scientific insight into the way populations of neurons interact in the complex, distributed systems that generate behavior. This review will address recent progress in cortical motor prosthetics.
