But people don’t actually show such tendencies toward either left- or right-brained activity, according to a study published last week (August 14) in PLOS ONE.
“It’s absolutely true that some brain functions occur in one or the other side of the brain.

It seems to be determined more connection by connection.”
Anderson and his colleagues analyzed functional magnetic resonance imaging (fMRI) data from the brains of more than 1,000 resting subjects. While the researchers found that various regions of...
