An artist's rendering of individual neurons. A new electrode developed at the University of Michigan can focus on the electrical signals of just one neuron. It may help researchers understand how electrical signals move through neural networks in the brain. Because this electrode is so small and unobtrusive, it may be able to stay in the brain for long periods without upsetting the immune system, perhaps picking up signals to send to prosthetic limbs.
