Instead of the brain moving largely in unison, an area deep in the brain called the corpus callosum - which connects the left and right halves of the brain — shakes more
rapidly than the surrounding areas, placing significant strain on those tissues.
Combining data recorded from football players with computer simulations of the brain, a team working with David Camarillo, an assistant professor of bioengineering, found that concussions and other mild traumatic brain injuries seem to arise when an
area deep inside the brain shakes more
rapidly and intensely
than surrounding areas.
