Such devices could lead to innovative treatments in humans for everything from blindness and paralysis to brain diseases such as Parkinson’s and Alzheimer’s. For now, the researchers are working in animals, and they are mostly just listening to neural activity to understand the brain. But because newly designed electrodes can carry inputs as well as outputs, the day when bioelectronics will not just monitor animal behavior, but also control it, is not far off. These advances are beginning to dissolve the boundary between living organisms and the outside world.
