Study finds notable difference in musicians’ brains: “Musical experience was strongly related to larger amounts of grey matter in the region called the Heschl’s gyrus, which is part of the auditory cortex. The structure contained 536 to 983 cubic millimetres of grey matter in professionals, 189 to 798 cubic millimetres in amateurs, and 172 to 450 cubic millimetres in non-musicians.” Ananova
