Man plays Guitar Hero for the first time in THREE years, thanks to brain chip

Five years ago, Ian Burkhart was left paralysed from the chest down after a diving accident. Today, he can pick up a coffee cup, swipe a credit card and even play air guitar - all by using the power of thought. The 24-year-old is the first person to be implanted with a brain chip that reads his mind, decodes the signals from his nerves and then uses the information to make muscles move. The milestone, reported in the journal Nature, spells hope for millions of paralysed people including victims of strokes. The doctors and engineers behind the breakthrough said: 'We think the sky is the limit.'
