Specimen: 3D rendering of Brainbow-labeled cerebral cortex of a mouse brain, showing multicolor pyramidal neurons. Brainbow is a process by which individual brain neurons are distinguished from one another. Neurons randomly express different colors, making it possible to flag each neuron with a distinctive color and follow its pathway through brain tissue.
Technique: Microscopy by wavelength mixing
