Human brain cut into 7,400 slices, then reconstructed digitally in 3-D
–
Scientists have finely sliced a human brain into 7,400 wafer-thin sheets and then digitally reconstructed it to create the world’s most detailed map of the brain in three dimensions. The “BigBrain” project, which took a 65-year-old woman’s brain and cut it into slices just 20 micrometers thick, shows the brain’s anatomy in microscopic detail, almost down to a cellular level, said the scientists who carried out the work. A micrometer, or micron, is a millionth of a meter, or less than a ten-thousandth of an inch. The resulting 3-D reference brain will allow researchers worldwide to study the organ in unprecedented physical detail, paving the way for deeper understanding of how processes like cognition and emotions work, and how brain diseases develop.
