Monkey with prosthetic hand gets sense of touch

Researchers are finding ways for artificial intelligent - started with  laying the groundwork for touch-sensitive prosthetic limbs that could transmit a sense of touch to the brain that bypasses regular routes. The team trained rhesus macaques to focus their gaze in different directions, depending on which finger was being prodded. The team recorded what activity occurred in the brain and where using microelectrodes placed in the macaques’ primary somatosensory cortex. They then stimulated the brain using the same patterns of activity and found the monkeys reacted as if they had been touched, fixing their gaze in the direction they had been taught.
