The latest version of a prosthetic hand that can provide real-time sensory feedback, enabling its user to control grasp, was presented at the AAAS.

Brain implants could allow people to 'feel' the presence of infrared light and one day be used to move artificial limbs. el Nicolelis, a neurobiologist at Duke University in North Carolina who led the work, is a pioneer in the development of brain implants that can be used to control computers or prosthetic arms by thought alone. 'This shows that the adult brain can acquire new capabilities that have never been experienced by the animal before,' he said. 'We could learn to detect other sorts of signals that we normally don't see or experience; the perceptual range could increase.' Because light travels so fast, the feedback from the artificial limbs would be even quicker than normal nerve impulses and the person using the prosthetic would simply 'feel' the movement of the bionic limb as a different type of touch.
