| Research Interests: My laboratory explores two different aspects of brain function. The first is how we are able to integrate the many different stimulus attributes into the percept of a single object or event. For example, when listening to someone talking, one perceives the sounds and sight of the person as a single entity. However, the nervous system processes this information initially completely independently; the cochlea processes the sound and the retina processes the sight completely independently of each other. How is this information then recombined? This is the broad issue that my laboratory is addressing. The second aspect has to do with the consequences of normal aging, particularly with respect to age-related hearing loss. As humans and other animals age, they not only begin to lose the ability to hear high frequencies, but also have increasing trouble understanding speech. This can be very devastating to the individual and cause social isolation. What happens to the brain as a function of normal aging is almost completely unknown in this regard, which is the issue that my laboratory is currently tackling. |
