A primary focus of our research
is to understand the neural basis of binaural hearing,
with a special emphasis on the processing of interaural time disparities
(ITDs). ITD is a major cue for localizing sounds along the azimuth.
To accomplish this goal, we have studied binaural processing at
each major level along the ascending auditory pathway, including
the superior olivary complex, dorsal nucleus of the lateral lemniscus,
inferior colliculus, auditory thalamus, and auditory cortex. |

Another research
interest is in the development of a non-invasive electro-audiometric
technique to assess hearing disorders in newborns and children.
The amplitude modulation following response (AMFR, a.k.a ASSR)
is a promising tool for assessing hearing on a frequency-by-frequency
basis. We assume that the AMFR may be a preferred alternative
to the click evoked auditory brainstem response (ABR) since its
frequency specificity can be controlled. |
