Document Summary
More structured pyramidal tracts and white matter bundles (earlier myelination) Larger cortical representations of the digits of one or both hands (depending on the type of instrument played) Improved auditory perception (pitch, speech related hearing, selective auditory attention) Improved top down and bottom up integration during perception. Changes limbic system functions (emotive aspects of cognition) Musical cognitions exercise neural information processing mechanisms that make possible. Prediction and expectation (due to intermediate level of information content) During the course of a musical work listeners create ongoing expectations about what particular tonal- rhythmic events are likely to occur next in the piece. The expected next-event is based upon the culmination of events that have occurred in the piece so far. If this expected event is delayed or fails to occur at all, then emotional arousal will be stronger than it would be if the event had occurred as predicted.
