Evans, researchers use a microtome to cut sections from a brain preserved in paraffin wax into slivers 20-micrometers thick, resulting in over 7,400 slices. A digital three-dimensional model called "BigBrain" was produced from the thousands of sections. Its resolution is finer than a human hair, so it can reveal clusters of brain cells and even some large individual cells. It is being made available to scientists around the world.

This image made from video provided by researchers shows a highly-detailed image of the hippocampus region of the human brain. The digital three-dimensional model called "BigBrain" was produced from the thousands of sections made from the brain of a 65-year-old woman. Its resolution is finer than a human hair, so it can reveal clusters of brain cells and even some large individual cells. It is being made available to scientists around the world.

NEW YORK (AP) ? Scientists have a new brain atlas to help them study their favorite organ. It's a digital, three-dimensional model called "BigBrain."
Its resolution is finer than a human hair, so it can reveal clusters of brain cells and even some large individual cells. It is being made available to scientists around the world.
To make the atlas, researchers sliced a cadaver brain from a 65-year-old woman into 7,400 thin sections, stained them to reveal tiny features, and scanned each one. Then they used computers to combine the scanning data into a 3-D digital model.
The researchers, from Germany and Canada, reported their work Thursday in the journal Science.
