Jackson Pollock, a great American painter of the 20th century, established a distinct way of painting that produced a major impact on the world of art. The brain mechanisms that process temporal structure in music (tempo, rhythm and meter) have been less investigated than those that underlie pitch perception. These elements could be regarded as a temporal ‘hierarchy’ somewhat analogous to pitch interval, melody and harmony in the pitch domain. Impaired detection of rhythmic changes has been described in left temporoparietal stroke and left hippocampal sclerosis, while other studies have not demonstrated laterality differences. However, functional imaging studies have demonstrated activity in the lateral cerebellum and basal ganglia during the reproduction of a rhythm, and there may be distinct representations for sequences with time intervals in integer ratios (more common in music) compared with non-integer ratios. The observed activation of motor structures suggests that the perception and production of rhythm … Read the rest
