Right- or Left-Brained? There's No Such Thing
Study finds we have no preference for one side over the other

(Newser) – If you've long lauded your powerful right brain for providing you with your artistic prowess, some University of Utah researchers have bad news for you: The whole right-brain/left-brain thing isn't true. The neuroscientists analyzed 1,011 brain scans to come to their conclusion about whether people are indeed right-brain (ie, creative) or left-brain (ie, logical) dominant, and uncovered no proof that we actually use one side of our brain more heavily or have more robust neural connections there, reports the Salt Lake Tribune.

To understand how the study worked, a quick science lesson/refresher: Lateralization is no myth, and refers to mental functions that largely rely on one side of the brain; for instance, speech is a mostly left-brain function, reports LiveScience. The scientists divided the brain into 7,000 regions and looked for connections. They counted the number of connections that could be described as left- or right-lateralized, and uncovered neither a preference for one side nor a stronger neural network on one side, reports Science Daily. "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," says one of the study's authors.

Perhaps not literally we're not right or left brained but the analogy still applies. Our brains are just very complex computers controlled by tiny switches that go on or off. Initially ones thinking then tends to be limited to categorizing our experiences as that way or this way. As our thinking becomes more complex and we gain experiences then the programming of the switches becomes much more complex as in a better computer program. Spacial thinking eventually results if we strive to continue learning, observing, listening, perceiving. Its quite rare in my experience.

They didn't mention that libs were excluded from the study because it required actually having a brain to participate...............
