Multifunctional fibers communicate with the brain

By producing complex multifunctional fibers that could be less than the width of a hair, MIT researchers have created a system that could deliver optical signals and drugs directly into the brain, along with a simultaneous electrical readout to continuously monitor the effects of the various inputs.
