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 ...

This is Video S1 and it corresponds to Figure 2A. It shows that local blebbistatin micropipetting, but not DMSO, increases spine formation and extension (arrowheads). Equal volumes of blebbistatin and...

This is Video S2 which corresponds to still images in top row of Figure 2D. It shows the spine dynamics of control neurons. Time-lapse confocal imaging was performed on DIV14 hippocampal neurons co-ex...

This is Video S3,which corresponds to still images in bottom row of Fig. 2D. It shows that knocking down levels of Myosin II B (MIIB) increases spine dynamics. Spines from MIIB knockdown neurons exten...

Time lapse recording showing the development of neuron polarity in a hippocampal neuron growing in vitro. This recording captures not only the formation of the axon (the longest process, oriented down...

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

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 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...
