Fluorescent lights depict the electrical firing of neurons in the brain in this striking video demonstration reported by Bloomberg. The technology was developed by Adam E. Cohen, PhD, a Harvard neuroscientist and professor of chemical biology and physics.

Being able to visually map the electrical activity of the brain with fluorescent light could be used to research neurological diseases such as multiple sclerosis and epilepsy. Biogen, GlaxoSmithKline and other biotech companies are already staking claims on future collaborations for drug discovery.
