The Washington Post reports that a 65-year-old woman’s brain was cut into 7,400 slices to create the most detailed three-dimensional atlas of the human brain ever made, bringing researchers one step closer to reverse-engineering the brain’s convoluted circuitry. Brain atlases are essential reference tools for researchers and physicians, to determine which areas are “lighting up” during a task or thought process, or during image-guided surgery. The better the atlas resolution, the better doctors can target ever-smaller parts of the brain and their individual function…
