Recent brain studies have resulted in a simpler way to look at the brain. This new brain scanning provides scientists with new clues to how the human brain is built and even how it evolved. The technique used by scientists from the Massachusetts General Hospital and Harvard Medical School is called diffusion magnetic resonance imaging. The mapping of these brain patterns in mammals may eventually lead to the ability for doctors to be able to diagnose brain disorders due to alterations in the patterns. An additional reason as to why this finding is so important is that studies can be performed to compare the evolutionary root of the brain to similar mammals to the human.
