Random Brain Activity

Laurel Trainor, director of the Institute for Music and the Mind at McMaster University in West Hamilton, Ontario, and colleagues compared preschool children who had taken music lessons with those who did not. Those with some training showed larger brain responses on a number of sound recognition tests given to the children. Her research indicated that musical training appears to modify the brain's auditory cortex. Can larger claims be made for the influence on the brain of musical training? Does training change thinking or cognition in general?

Trainor again says yes. Even a year or two of music training leads to enhanced levels of memory and attention when measured by the same type of tests that monitor electrical and magnetic impulses in the brain.
