This is a rendering of part of a large scale, 3-D, multicolor image of a piece of the mouse hippocampus. Neurons express differently colored fluorescent proteins through a technology called Brainbow, in which viruses deliver the genes that encode for different fluorescent proteins to different neurons. This brain was prepared using expansion microscopy.
