Myth: some people are left brain, and some are right brained
For years\' people, have been asked if they are left-brained or right-brained and it has been widely believed that we are either or. For some reason people, have categized themselves into these two groups, but why? Where did this notion start from and why has it become so widely believed or accepted to be correct? Popular culture would have you believe that logical, methodical and analytica l people are left-brain, and the creative and artistic types are r ight-brain dominant. The with that is, science never supported this notion. With the media having a big effect on the public, by falsely stating that people are left-brained or right-brained, there is no question why people believe that. To end all speculation on this myth, it is being stated right here that we are not left or right brained but in fact we are equally right and left brained and not more dominant on either side.
Scientist at the University of Utah have now debunked this myth that has been around for so many years, they did an analysis on over 1,000 brains and the results that came back were that there was no evidence that showed that people used their left or right brain preferably over the other, but in fact during the study people used their entire brain equally throughout the experiment. (Dr. Jeff Anderson) Dr. Anderson\' s experiment consisted of 1,000 brains from test subjects ranging from ages of 7 to 29, and what he did was look at the activity of over 7,000 small brain regions and examined neuron connections within and in between these regions. They did find certain areas having stronger neurons traffic than other, over all they came to the conclusion that both sides of the brain have the equal amount of neuron activity and connectivity. Jared Nielsen who was one of the co-authors on the research stated "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."
This myth of people being left or right-brained may have come from a Nobel prize winning research published by Roger Sperry, which was conducted in the 1960\'s. Roger Sperry\'s study was conducted with patients who had epilepsy who had surgery done that consisted of the patient\'s corpus callosum being cut in half. Due to the corpus callosum being cut in half the left hemisphere was not able to communicate with the other hemisphere, thus meaning both halves of the brain were unable to communicate with each other. Sperry then proceeded to conduct a bunch of clever studies and was then able to determine which sides of the brain were involved with math, language, drawing and other functions. Psychology enthusiasts begin to run with this idea, thus creating the myth that personality and other tributes were determined by which side of the brain is dominant over the other. (livescience.com) the neuroscience community never believed in that belief but the public and media very much bought into the idea of it. Anderson was able to debunk this theory by showing the neuroscience community his studies and saying "now we have evidence from over 1,000 brain scans showing no left or right dominance in the brain at all"
So, when going over Anderson\'s study, showing that in a group of 1,000 people, nobody has a brain that has one side more dominate than the other . Due to the media and psychology enthusiasts making false statements about the brain, it has lead people throughout time believing that one side of your brain is more dominate than the other. Making people believe that they have their type of personality due to one side of the brain being stronger, and having people group themselves by which side of their brain is stronger. Now there is proof that this myth is false and we have 1,000 brains to proof it with.
