• Human brain cut into 7,400 slices, then reconstructed digitally in 3-D
  LONDON — 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 so-called "Big Brain" 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 ...
