| Outline of Final Research Achievements |
This work investigated the utility of scalp-recorded auditory event-related potentials (ERPs) for investigating the human evolution of music. ERPs to various sounds, from pure tone to musical chord progressions, were recorded in human and non-human primate species to investigate species differences in how these sounds are processed in the brain. Results suggested that the time scale of auditory cortical processing is elongated in humans, which would enable neural representations of complex auditory features that characterize music and language.
