Music and Auditory Neuroscience Laboratory
Our Laboratory investigates the brain mechanisms that underpin human hearing. We use a range of behavioural, cognitive, computational, and neurobiological techniques to explore the auditory system in healthy and clinical populations. In particular we use music to study how the brain learns complex auditory tasks and responds emotionally to information.
We apply this fundamental knowledge to develop new theories of music perception and cognition, and new approaches to music practice in education, communities, performance excellence and health. Some examples of research we are undertaking include:
- Sound recognition mechanisms and their role in auditory perception
- The perception of pitch and dissonance, including absolute pitch (AP)
- Learning mechanisms and brain plasticity involved in music perception and performance associated with music training
- The use of music to aid recovery after brain injury, and regulate mood and social behaviour
- The development of new musical instruments and notational systems
We have also investigated auditory processing in a range of neurological conditions, such as autism spectrum disorders (ASD), epilepsy, schizophrenia, and Williams Syndrome. Our computational models of the auditory system have formed the basis of new patented algorithms for de-noising speech signals and for speech and sound recognition.
