Nanometric Light Modulators Used to Study Deep Regions of the Brain

Scientists can depend on a formidable tool — light — when it comes to recording and stimulating brain activity. An international team of researchers, directed by Istituto Italiano di Tecnologia (Italian Institute of Technology/IIT), has created nanometric light modulators that, built on a micrometric optical fiber, make the fiber capable of analyzing neuronal tissue in deep regions of the brain.
