Implanted And Attached Instrumentation

Miniaturized electronics and device technology (e.g., nanotechnology) offer the promise of overcoming some of the deficits produced by brain damage. Sensors and stimulators have been implanted in the brains of blind and paralyzed persons to interface with computers. An array of electrotactile stimulators built into a false palate (similar to an orthodontic retainer) may allow the tongue to act as a human-machine interface for information from many proposed artificial receptors, such as a TV camera for blind persons, a pitch-and-roll sensor for persons who have lost vestibular function, or a robotic hand with position and touch sensors for paralyzed brain and spinal cord-injured persons. These are examples of the application of emerging technologies to compensate for functional loses.
