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"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...

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...

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...

Confocal micrograph of the brain of a transgenic zebrafish embryo. Some neurons express the green fluorescent protein (GFP) - shown in green under the control of a specific promotor. Tracts, axons and...

Confocal micrograph of the anterior region of the developing zebrafish brain (consisting of the telencephalon, part of diencephalon and the optic tectum). Some of the neurons (shown in green) express ...

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)...

Platinum replica depicting the cytoskeletal organization of dendritic spines in extracted 14 DIV neurons. This image shows the interaction of putative PSD from the spine head with axonal intermediate ...
