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...

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...

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...

Fluorescence micrograph of a neuron regenerating in culture. Honorable Mention, 2006 Olympus BioScapes Digital Imaging Competition.

Confocal micrograph of “lost” axons - chick interneurons labeled with green fluorescent protein that were transplanted from older into younger embryos. When they encounter unfamiliar territory, th...

Confocal micrograph showing nerve cells growing along fibers (purple) made from a specially modified silk that is similar to that made by spiders and silkworms. Schwann cells, whose nuclei are shown i...

Colorized transmission electron micrograph of a platinum replica showing the cytoskeletal organization of stubby dendritic spines in extracted hippocampal neurons after 14 DIV. This imge shows branche...

Platinum replica depicting the cytoskeletal organization of dendritic spines in extracted 14 DIV neurons. Mushroom spines associate with dendrites at the base (bottom) and with axons by the head (top)...
