Today’s neural implants are smaller than ever, but often remain cumbersome and prone to complications. According to researchers at Cornell University, a new iteration detailed this week in the journal Nature Electronics may offer a novel path forward for brain implants. “As far as we know, this is the smallest neural implant that will measure electrical activity in the brain and then report it out wirelessly,” electrical engineer and study co-author Alyosha Molnar said in a statement. One major drawback to most current brain implants is that they cannot function when a patient undergoes electrical monitoring like during an MRI. “One of the motivations for doing this is that traditional electrodes and optical fibers can irritate the brain.
