This New Tool Lets Scientists Watch the Brain Think

Scientists have turned brain cells into tiny light sources, revealing the brain at work like never before. About ten years ago, scientists began exploring an unconventional idea for studying the brain: using bioluminescent light to make neural activity visible. Instead of shining light onto the brain from the outside, they wondered if neurons could be [...]
