## Scientists create a needle-thin brain implant that can do three jobs at once ## Scientists have created a flexible, needle-thin brain implant that can record signals, deliver drugs, and stimulate multiple brain regions at once. A new type of brain implant could give scientists a more precise way to study the brain and may eventually contribute to treatments for neurological conditions such as epilepsy. Researchers from DTU, the University of Copenhagen, University College London, and other institutions have developed a long, needle-thin brain electrode equipped with microscopic channels.…
