The Neural Substrates of Tonality
with Amanda Marquiz, Daniel Stehr, Xiaojue Zhou, Jon Venezia, Kayoko Okada, Charlie Chubb, Greg Hickok, and Emily Grossman
The aim of this project is to use functional neuroimaging (fMRI) to compare the patterns of brain activity in listeners with high vs. low scale-sensitivity to tone-scramble stimuli. The divide in performance amongst listeners in previous studies suggests that some possess neural substrates that are differentially activated by these two classes of stimuli. This project will (1) determine where in the brain these regions are, and (2) whether specific regions or distributed patterns of brain activity are differentially activated between listeners high and low in scale-sensitivity.
