Scientists found more grey matter in the auditory cortex of the right hemisphere in musicians compared to nonmusicians. They feel these differences are probably not genetic, but instead due to use and practice.
Listening to classical music, particularly Mozart, has recently been thought to enhance performance on cognitive tests. Contributors to this volume take a closer look at this assertion and their findings indicate that listening to any music that is personally enjoyable has positive effects on cognition. In addition, the use of music to enhance memory is explored and research suggests that musical recitation enhances the coding of information by activating neural networks in a more united and thus more optimal fashion.
