A wireless sensor implanted in animals successfully monitored brain activity for more than a year, marking important progress toward the development of wireless technology that would allow thought control of advanced prosthetic devices. "Brain-computer interfaces harness existing brain circuitry, which may offer a more intuitive rehab experience," said Grace Peng of the National Institute of Biomedical Imaging and Bioengineering. The NIH funded the research at Brown University, and the results were published in the Journal of Neural Engineering.
