Research Topic: Electrophysiological characteristics in children with auditory neuropathy spectrum disorder
Long-Term Goal: To use objective techniques to further target and investigate physiologic properties of the auditory system, which can be used to better understand the underlying lesion/impairment; and to improve clinical cochlear implant mapping strategies for children with ANSD through the information gleaned from objective electrophysiologic testing.
