Research Summary

Our laboratory uses an integrated approach of psychophysics, electrophysiological recording, neuroanatomical approaches, and functional imaging to examine multisensory processing in the auditory cortex. The lab pioneered the use of focal cooling to reversibly deactivate regions of the cerebrum. Work in the lab examines cortical plasticity in the presence and absence of acoustic input, and following the initiation of auditory processing through the use of cochlear prosthetics.

Research Questions

How does experience influence brain development and influence adaptive neuroplasticity?

In order to answer this question we are presently pursuing three different avenues of investigation:

  • Cortical Processing and Organization in the Hearing Subject
  • Cortical Processing and Organization in the Congenitally Deaf
  • Cortical Processing and Organization in the Deaf Following Cochlear Implant
