Presentation Title: Mapping the cortical dynamics of auditory attention for a next-generation hearing aid design
Speaker: Associate Professor Adrian KC Lee
Date: Monday 11 July 2016 , 10.30pm to 12pm
Australian Hearing Hub, lecture theatre, level 1

Abstract: Spatial cues play an important role in segregating auditory objects in a complex acoustical scene. Spatial attention is often considered to be supramodal, e.g., crossmodal spatial cues can enhance the perception of stimuli in another modality when presented in the same location. How similar is the auditory spatial attentional network compared to its visual analog? How does the supramodal spatial attention network function if the listener attends instead to non-spatial acoustic features, e.g., pitch? In this talk, I will describe a series of studies that investigate different aspects of auditory spatial attention by combining magneto- and electro- encephalography, constrained by anatomical MRI data. I will also discuss the similarities and differences in cortical regions recruited for auditory spatial and non-spatial attention during both maintenance of attention on an auditory stream and switching of attention between streams. Finally, I will talk about our ongoing neuroengineering effort to capitalize on the findings from these neuroimaging experiments to create a next-generation hearing-aid that can selectively amplify the speech signal of interest according to user intent.
Bio: Adrian KC Lee is an Associate Professor in the Department of Speech & Hearing Sciences and at the Institute for Learning and Brain Sciences at the University of Washington, Seattle, USA. He obtained his bachelor’s degree in electrical engineering at the University of New South Wales and his doctorate at the Harvard-MIT Division in Health Sciences and Technology. Dr. Lee’s research focuses on developing multimodal imaging techniques to investigate the cortical network involved in auditory scene analysis and attention, especially through designing novel behavioral paradigms that bridge the gap between psychoacoustics and neuroimaging research
