What do we do?

We are interested in neural mechanisms that control the voice.

For the last 15 years we have studied how auditory feedback is used for vocal control.

We electronically change the pitch or loudness of a person’s voice auditory feedback, and this results in a reflexive response to the change in pitch or loudness. Link to paradigm.

We now use fMRI and EEG techniques to study brain mechanisms involved in this reflexive system.

Why do we do this?

There are many neurologically based voice disorders that are poorly understood. We anticipate that learning about brain mechanisms controlling the voice will help us understand some of these disorders. With greater understanding we hope to develop better techniques to diagnose and treat these disorders.
