A prosthetic hand that is connected directly to the brain successfully enabled a paralyzed man to "feel" again, according to researchers at the Defense Advanced Research Projects Agency (DARPA).
The 28-year-old male, who suffered a spinal cord injury and has been paralyzed for more than a decade, was able to control a robotic hand with his brain and reported being able to sense physical sensations.
DARPA researchers attached electrodes to the man's sensory cortex — the area of the brain responsible for identifying tactile sensations, such as pressure. Electrodes were also placed on the patient's motor cortex, the part of the brain that directs body movements.
