Brain chip allows paralysed man to post first ever 'direct-thought' tweet

The Independent - Tech 

A paralysed man has made the first "direct-thought tweet" after having a computer chip implanted in his brain. Philip O-Keefe, a 62-year-old Australian who suffers from amyotrophic lateral sclerosis (ALS), composed and posted the tweet using only his thoughts via a brain computer interface developed by neurotech startup Synchron. I created this tweet just by thinking it," stated the tweet, which was posted to the account of Synchron CEO Thomas Oxley. After sharing the initial tweet, Mr O'Keefe posted seven further tweets replying to questions from Twitter users. "My hope is that I'm paving the way for people to tweet through thoughts," the final one stated.

It was inserted through the jugular vein in order to avoid invasive brain surgery, and has since allowed him to reconnect with loved ones and colleagues via email, as well as play simple computer-based gamed like Solitaire. "When I first heard about this technology, I knew how much independence it could give back to me," Mr O'Keefe said after posting the tweet, according to a press release from Synchron. "The system is astonishing, it's like learning to ride a bike – it takes practice, but once you're rolling, it becomes natural.
