For the first time, U.S. scientists have induced natural sensations in a paralysed man's arm by electrically stimulating a certain region of the brain. The somato sensory cortex is a strip of brain that governs bodily sensations. Caltech Scientist implanted electrodes in brain's somato sensory cortex. The patient has a high-level spinal cord lesion and not being able to move his limbs, also cannot feel them. Electrodes were able to stimulate neurones that produced physical sensations. The work could allow patients using prosthetic limbs to feel physical feedback from sensors on these devices, noted scientists.
