Brain-computer interfaces that can translate thoughts into actions will change how stroke patients, paraplegics and other people with limited mobility interact with their surroundings. But so far, these devices have involved bulky corded equipment inside research labs, requiring patients to be tethered to a computer. Now researchers at Brown University have built the first wireless version. Like a cellphone embedded in the brain, their new implantable brain sensor can relay broadband signals in real time from up to 100 neurons
