Scientists induce sensation of touch in paralysed man's arm
In a first, Caltech scientists have induced natural sensations in a paralysed man's arm by electrically stimulating a certain region of the brain. Electrodes implanted in brain's somatosensory cortex 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.
