For years, we have been led to believe that right or left brain dominant can determine your personality. If you’re right brain dominant, you might not be so organized, but you’re creative. If you’re left brain dominant you’re more likely to be a math whiz. It’s a concept that has always made sense because different sides of the brain determine different tasks that we set out to do. Left handed; the right side of the brain works first.
New research has found that there is no such thing as right or left brain dominant, and it’s disrupting the way of thinking of more than one right-brained thinker. The study took place over the course of two years at the University of Utah, and researchers that took on the project now believe that they have officially debunked the myth once and for all.
The team was able to identify the exact networks in the right and left sections of the brain that do the processing for functions that are “lateralized.” What this means, in lay-terms, is that there are certain functions that take place in the brain only in one part of it. For instance, language often happens on the left side of the brain and attention comes from the right side of the brain.
In order to determine which functions occurred in what part of the brain, researchers studied the brain scans of over 1,000 people that ranged in age from seven to 29. They looked at the “lateralization” of the brain for each person and discovered that none of the participants used one side over the other more often.
Jeff Anderson, the lead author of this study, has said that it is particularly true that some functions of the brain occur in one side over the other side of the brain, but people don’t seem to have a preference when it comes to what side of the brain they use. The side of the brain that is used tends to be determined more by what the connection is.
The brain scans studied the resting brain activity.
It may be what life exposes us to that causes a certain side of the brain to work more than the other, depending on the functions of the brain that we need to perform throughout the day. Creative professions might use the area that focuses on creation of all kinds, where those in a profession that is more analytical might use more of another part of the brain.
