If you want to get your hands on a human brain to study, your options are very limited. Obviously, acquiring a healthy brain is impossible if a person is still alive, so researchers must limit themselves to post-mortem dissections in order to understand the physical makeup of the brain. But new technologies are changing that in ways you might not expect. The image above is a 3D printed model of a healthy human brain. One team of researchers took high resolution MRI scans of one of their colleagues, and compiled a 3D model of the outer tissue of the brain. After a trip to the 3D printer the researchers could hold a very accurate facsimile of their friend’s brain. While scientists are only beginning to explore the applications of such technology, this seems to offer an intimate view of the brain — one which a person would be lucky to get while alive.
