Feel Touch on Robotic Hand

For the grand test, they blindfolded the subject and hooked him up to a robotic hand. When they pressed one of the fingers of the hand, it
communicated with the implant, which fired the neurons in the region of the brain corresponding to that finger. At first, the patient was able to correctly identify the location about 85 percent of the time. Then, as he got used to it, he reached 100 percent.“
