Research Interests

Mapping and exploring the functions of human brain regions responsible for our ability to recognize every day natural sounds (complex sounds) and our ability to localize sound in three-dimensional space. Additionally, we are exploring how auditory information becomes integrated with the other sensory modalities (i.e. vision and touch/motor).

Description of Techniques

We primarily use functional magnetic resonance imaging (fMRI), with the 3T scanner at the Center for Advanced Imaging.We also use neurophysiological techniques such as collecting evoked response potentials (ERPs) from the brain in response to hearing complex sounds; using transcranial magnetic stimulation (TMS) to interfere with putative auditory processing pathways in the brain; and psychophysically testing the perceptual attributes of various types of natural and synthetic sounds.
