Brainbow: In this mouse brain, each nerve cell glows a different color, earning it the nickname “brainbow” mouse. This microscopic image shows a bundle of neurons coming into a part of the cerebellum (thin lines from upper right to center). The neurons end in a tiny flower-like structure (colored splotches in center). Here, they link to another type of neuron, which carries signals to another part of the brain (thin lines around the center). Because each neuron is a different color, biologists can follow each on its tangled path. This, they hope, will yield insights into how the nervous system is wired and perhaps shed light on diseases that cause it to malfunction.

The field of splotches across the middle of the image evoke Claude Monet's impressionistic brushwork. The rich colors -- from fiery reds to grass greens and sky blues -- would be at home in his famous painting of a sunny poppy field near Argenteuil , France. (Full article: 1174 words)
