Cochlear implantation during vestibular schwannoma removal and labyrinthectomy for treatment of meniere’s disease
This study is designed to use both psychophysical and electrophysiological measures to evaluate temporal encoding and processing at both the peripheral and the central levels of the auditory system in adult cochlear implant users. The long-term goal of this research is to better understand the neurophysiologic basis of speech perception deficits in older (≥ 65 years) CI users. This investigation is being led by Dr. Shuman He and is currently funded by the NIDCD.
