Are you left brained or right brained? If you are predominantly logical, you are meant to be left brain dominant, the creative types… well, they are right brained. Or are they? Research out of the University of Utah shows NO EVIDENCE that your brain is as lateralized as you might believe…
Aug. 14, 2013 — Chances are, you’ve heard the label of being a “right-brained” or “left-brained” thinker. Logical, detail-oriented and analytical? That’s left-brained behavior. Creative, thoughtful and subjective? Your brain’s right side functions stronger — or so long-held assumptions suggest.
But newly released research findings from University of Utah neuroscientists assert that there is no evidence within brain imaging that indicates some people are right-brained or left-brained.
For years in popular culture, the terms left-brained and right-brained have come to refer to personality types, with an assumption that some people use the right side of their brain more, while some use the left side more.
Following a two-year study, University of Utah researchers have debunked that myth through identifying specific networks in the left and right brain that process lateralized functions. Lateralization of brain function means that there are certain mental processes that are mainly specialized to one of the brain’s left or right hemispheres. During the course of the study, researchers analyzed resting brain scans of 1,011 people between the ages of seven and 29. In each person, they studied functional lateralization of the brain measured for thousands of brain regions — finding no relationship that individuals preferentially use their left -brain network or right- brain network more often.
Results of the study are groundbreaking, as they may change the way people think about the old right-brain versus left-brain theory, he said.
“Everyone should understand the personality types associated with the terminology ‘left-brained’ and ‘right-brained’ and how they relate to him or her personally; however, we just don’t see patterns where the whole left-brain network is more connected or the whole right-brain network is more connected in some people. It may be that personality types have nothing to do with one hemisphere being more active, stronger, or more connected,” said Nielsen.
