Who doesn’t love brainbow?
For people who don’t know, brainbow is a type of stain created by a researcher at Harvard. Essentially, differing amounts of flourescent proteins in every single cell mean that each neuron is a different color. This means it is much easier to follow a single neuron along the axon and dendrites and see where it connects to, etc. since all the surrounding cells are different colors. I just love the way it looks!
