Neurons that glow in the dark.

Vanderbilt scientists have developed a bioluminescent sensor that causes individual brain cells to glow in the dark and allow us to trace what’s happening in large neural networks in the brain. To create the new sensor, rerearchers first genetically modified a type of luciferase obtained from a luminescent species of shrimp so that it would light up when exposed to calcium ions. Then they attached a virus that infects and genetically modifies neurons, lighting up our brains.
