A cross-section of a rat brain depicts cells (in blue) expressing normal levels of the Huntingtin gene while cells (in red) have had the gene knocked out. The latter cells, without the Huntingtin ...

"In the normal person the frontal lobe is one of the most highly active areas of the brain," says Buchsbaum, calling up an image on his computer. He points at a brightly colored cross-section of a ...

And when the researchers did that, the picture of "normal" brain development changed dramatically. For instance, when the sample reflected the U.S. population, children's brains reached several ...

Physical activity reorganizes the brain so that its response to stress is reduced and anxiety is less likely to interfere with normal brain function, according to a research team based at Princeton ...

The colorful glow in this mouse brain cross section comes from fluorescent proteins taken up by neurons in the motor cortex and transported along the brain's pathways. The image is part of a ...
