Abstract
Attention is critical to our ability to listen and communicate effectively. This project will determine the mechanisms by which feature-based attention shapes the processing of sound to understand how we are able to ‘tune in’ to a particular sound in a mixture. We will train human and ferrets in an identical task that requires they track an attended stream in a mixture. During behavior we will record single neuron responses and local field potentials in ferrets, and use EEG and fMRI in humans to record neural activity across spatial scales.
