Abstract

The effects of mild systemic hypoxia on inner haircell (IHC) and outer haircell (OHC) function were investigated in adult chinchillas free from ear disease. IHC/cochlear afferent function, as reflected in measured neural evoked responses, are found more sensitive to prolonged mild cochlear hypoxia than the activity of OHCs, as revealed in measured otoacoustic emissions. That hypoxia can have an initial effect on the INC/cochlear afferents confirm that it is an important etiological factor in some types of auditory neuropathy.
