High School Football and the Brain (IMAGE) University of California - Berkeley Caption Magnetic resonance imaging (MRI) brain scans have revealed that playing a single season of high school football can cause microscopic changes in the grey matter in young players' brains. These changes are located in the front and rear of the brain, where impacts are most likely to occur, as well as deep inside the brain.
