Research from the University of Zurich shows that each individual’s brain anatomy is as unique as a fingerprint, according to a summary in Science Daily.  Researchers have long known than individual parts of the brain shift with use.  The part of the brain responsible for finger movement, for example, will differ in the brain of a pianist from the general population.   Researchers have also known that function may shift.  For example, the part of the brain normally dedicated to vision may shift in a blind person to accommodate other sensory input, such as learning to  read Braille.  Now, researchers confirm what many have long suspected, that both genetic and environmental factors contribute to our brain’s individualized structure.
