Confocal image of "Brainbow" mouse cerebral cortex. In Brainbow mice, neurons randomly choose combinations of red, yellow and cyan fluorescent proteins, so that they each glow a particular color. Thi...

Sensory axons (long, slender nerve fibers) covering the tail of a 3- day-old larval zebrafish. This "Brainbow" image was collected using confocal microscopy. In the Brainbow technique (Nature, 2007), ...

Confocal image of an axonal rainbow of oculomotor nerve motor axons from a "Brainbow" mouse brain, with each neuron expressing a distinct color. In Brainbow mice, neurons randomly choose combination...

"Brainbow" zebrafish. Neurons are labeled in multiple colors with "Brainbow" (Nature, 2007) fluorescence microscopy. Three fluorescent proteins (cyan, yellow, and red) are randomly taken up by vari...

Confocal"Brainbow" mouse hippocampus and cerebral cortex neurons, with several fields montaged together. In Brainbow mice, neurons randomly choose combinations of red, yellow and cyan fluorescent pro...

Montage image of a brain stem from a Brainbow transgenic mouse. In Brainbow mice, neurons randomly choose combinations of red, yellow and cyan fluorescent proteins, so that they each glow a particular...

Confocal image of pastel neurons in the hippocampus of a "Brainbow" mouse brain, with each neuron expressing a distinct color. In Brainbow mice, neurons randomly choose combinations of red, yellow a...

CFP-expressing neuron, 14 days in vitro. By two weeks, cultured hippocampal neurons have developed a morphology typical of mature neurons with an extensive axonal arbor, a tapered and branched dendrit...
