Are groovy brains more efficient?

Kevin Weiner, associate professor of neuroscience and psychology, and colleagues have discovered that the depth of some of the smaller grooves in the brain, called tertiary sulci, are linked to stronger network connectivity and better reasoning ability in children and adolescents. The study, which was a collaboration with Silvia Bunge, professor of psychology, was published in The Journal of Neuroscience on May 19. The researchers hypothesize that the deeper grooves may pull connected brain areas closer together, resulting in more efficient communication between regions. Read more from UC Berkeley News.
