File this under “science we’d love to see onscreen.” Researchers at Harvard University genetically altered neurons to light up as they fire. Imagine, for a minute, your brain covered in bursts of light, like a fireworks show under your skull.
The researchers altered brain cells with a virus containing a gene from a Dead Sea organism. The gene produces a protein that, when exposed to an electrical signal, fluoresces. The virus introduces the gene to the brain cells, which are cultured in a lab, causing the cells to produce the protein, which lights up as the neurons fire.
