Although commentators and pro football itself have argued that rule changes by the National Football League have notably reduced possible head harms, new evidence from college athletes shows that even knocks that aren’t severe enough to be deemed concussions may injure young brains.
Those findings come from a University of Rochester study based on brain scans and helmet data from members of the school’s Division III football team (shown above), the New York Times reported.
Researchers scanned the athletes’ mid-brain area twice, once before the season kicked off and at its end. They did so because that region would most likely show the effects of impacts, including those that might be tougher to gauge in other areas of the brain. They also compiled data from special equipment on players’ helmets, registering the number and intensity of every impact — not just from player collisions but also when athletes hit the ground.
