Attentional Modulation of the Inner Ear: A Combined Otoacoustic Emission and EEG Study
TL;DR: Both enhanced processing of attended acoustic stimuli in early sensory cortex and reduced processing of distracting input are shown, both at higher cortical levels and at the most peripheral level of the hearing system, the cochlea.

Contralateral Acoustic Stimulation Modulates Low-Frequency Biasing of DPOAE: Efferent Influence on Cochlear Amplifier Operating State?
TL;DR: The experimental results were in good agreement with a simple model of distortion product generation and suggest that the olivocochlear efferents might change the operating state of cochlear amplification.

Cochlear sensitivity in the lesser spear-nosed bat, Phyllostomus discolor
TL;DR: The results indicate that in P. discolor, cochlear sensitivity, as assessed by DPOAE recordings, does not show a threshold maximum at 55 kHz, and the characteristic pattern of subsequent threshold maxima and minima at high frequencies observed in behavioral studies seems to be shaped by transfer characteristics of the outer ear and/or neuronal processing in the ascending auditory pathway rather than by co chlear mechanics.

Influence of contralateral acoustic stimulation on the quadratic distortion product f2-f1 in humans.
TL;DR: The observed sensitivity of f2-f1 to contralateral noise stimulation could hence be resulting from a shift of the operating state and/or a change in the gain of the cochlear amplification due tocontralateral induced efferent modulation of the outer hair cell properties.

Effect of contralateral pure tone stimulation on distortion emissions suggests a frequency-specific functioning of the efferent cochlear control
TL;DR: The frequency-specific effect of CAS with pure tones suggests a dedicated central control of mechanical adjustments for peripheral frequency processing in the gerbil.
