Listening, as distinct from hearing, requires that the brain makes sense of the complex mixture of sound that enters our ear and arranges these sound elements into sources, such as the voice of your friend, or the hiss of a coffee machine. To listen effectively requires effective auditory processing, combined with selective attention and even multisensory integration. My lab asks how are complex sound features represented in and beyond auditory cortex, and how do non-auditory factors influence this. We combine behavioural work in humans and animals with neurophysiological recordings, perturbation of neural activity and computational methods.
