Spontaneous Otoacoustic Emissions Reveal an Efficient Auditory Efferent Network

Conclusions The results suggest that even the earliest stages of speech comprehension are modulated by top-down influences, resulting in changes to SOAEs depending on the presence of bimodal or unimodal input. Neural processes responsible for changes in cochlear function are sensitive to redundancy across auditory and visual input channels and coordinate activity to maximize efficiency in the auditory periphery.
