NIH NIDCD: Auditory Scene Analysis and Temporal Cortical Computations

Faculty 

Funding Agency 

National Institutes of Health National Institute on Deafness and Other Communication Disorders

Description 

Simon will use magnetoencephalography (MEG) to record from the auditory cortexes of the brains of human subjects, specifically the temporally dynamic neural responses to individual sound elements and their mixtures. Linking the neural responses with their auditory stimuli and attentional state will allow inferences of neural representations of these sounds. These neural representations are temporal: neural processing unfolds in time in response to ongoing acoustic dynamics. Simon will determine how the auditory cortex neurally represents speech in difficult listening situations.

This is a National Institutes of Health National Institute on Deafness and Other Communication Disorders R01 grant, "Auditory Scene Analysis and Temporal Cortical Computations." The five year, $1.5M grant started March 1, 2015. The research will further the understanding of how in an environment with many sounds and voices, people are able to concentrate on an individual voice and what it is saying.
