Brain implant lets paralyzed people turn thoughts into text

Three people paralyzed from the neck down have been able to use unmodified computer tablets to text friends, browse the internet and stream music, thanks to an electrode array system called BrainGate2. The findings could have a major impact on the li...

Paralyzed man first to move his arm by thinking about it

Helping paralyzed people move on their own has been a lot tougher than 1970s TV shows led us to believe it would be. For what they believe is the first time, researchers used tech to bypass a quadriplegic patient's severed spinal cord, helping him mo...

Harvard lets human minds control rats, private rodent armies remain distant (video)

Harvard links human and rat minds, Pied Piper no longer required

Sure, we've seen rats control other rats, but that won't give us a legion of mind-controlled creatures to unleash upon an innocent public, will it? Harvard Medical School may unwittingly assist with solving our (rather misguided) plight, as it just experimented with a system that lets a human mind trigger actions in a rat's motor cortex. The test had sensor-equipped humans watch a screen that flashed in sync with their EEG brain patterns for visual stimulation; as soon their attention shifted to controlling the rat, they triggered an ultrasonic pulse that twitched the rodent's tail. There's a few problems with the implementation beyond the obvious lack of autonomy for the poor target creature, though. The rat's anaesthetized state likely affected the results, and the system isn't currently sophisticated enough to map specific thoughts to corresponding actions. The Harvard team is working to refine the technology, however, and there may be a day when we can satisfy our megalomania... or at least, put the Pied Piper on notice.
