One Less Excuse

Those of us who like to believe we are artistic and creative because we are left-brained or that we are analytical and that we reason logically because we are right-brained may be disappointed to learn that these explanations may be more myth than fact.

With the ability to collect data from neuroimaging in brain scans, scientists have observed that the functional connectivity and networking within brain functions are not concentrated in a specific hemisphere of the brain based upon the type of activity a person is performing. In a study out of the University of Utah, researchers found that there is little evidence that one side of the brain has a stronger influence upon our personalities or interests than another.

In other words, the functional network system of the brain seems to be so interconnected that many personality traits, strategies for thinking or creating, or personal areas of interest cannot be attributed to the stronger lateral side of our “gray matter.”  It’s not uncommon to hear individuals use the mythic right-brain left-brain theory to support certain abilities or account for specific deficiencies, e.g. reading or mathematics.  This study, however, casts doubt on such claims.  In fact, both hemispheres of the brain are tightly connected and are necessary for proper functioning.  Remember that next time you hear someone say they ‘don’t do math’ because they’re a right brained person.  That reasoning appears to be a fancier, dressed-up version of the idea that they lack the ‘math gene’ or they lack mathematical reasoning as an innate ability.  Math and reading, like any skill, can be learned and improve with practice.
