A compact, self-contained sensor recorded and transmitted brain activity data wirelessly for more than a year in early stage animal tests, according to a study funded by the National Institutes of Health. In addition to allowing for more natural studies of brain activity in moving subjects, this implantable device represents a potential major step toward cord-free control of advanced prosthetics that move with the power of thought. The report is in the the Journal of Neural Engineering.
Wouldn’t it be great if you could control your PC with your brain? Well, this sort of thing may be closer than you think.
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
This is a preview of Monkeys and Pigs control Computers wirelessly using Brain Signals.
