Over the brainbow

That's not an abstract expressionist painting up there, but rather an image of neurons in the hippocampus of transgenic mice, which are randomly expressing proteins in different fluorescent colors. Using recombinant genetic techniques, scientists at Harvard have spliced genes from coral and jellyfish into developing mice to produce up to 90 different colors in their neurons. Some surprising neural patterns have already been discovered using the technique, which has been dubbed "Brainbow."
