A Woman's Brain Was Sliced Into 7,400 Pieces For Science [PHOTOS]
While previous brain models only allowed viewers to see the visible brain, the so-called BigBrain model allows researchers to see clearly see details down to 20 microns (less than the width of a human hair).
The team of German and Canadian scientists affiliated with the European Brain Project used a brain donated by a 65-year-old woman for the project. They encased it in paraffin wax (the same substance used to make many candles) and sliced it into 7,400 extremely thin cross sections.
They stained these cross sections to show brain structure, scanned them into a computer and reassembled them into a fully-coherent 3-D image, which you can navigate on your computer:
BigBrain
BigBrain is the work of the European Human Brain Project, and involved efforts by scientists in Germany and Canada.
"This allows us a completely new level of insight into the brain’s organization," study researcher Alan Evans, of McGill University, said during a press conference June 19. "So we’ve raised the level of insight, orders of magnitude beyond what was possible at the turn of the 20th Century. This data set will revolutionize our ability to understand internal brain organization."
The new model will allow scientists to study everything from how healthy brains develop to how brain diseases like Alzheimer's progress.
BigBrain is available for free online, but you have to apply and be approved by the project team before you can use it. Here's a preview of what it's like to zoom through the brain:
