The ability to navigate “cocktail party” situations by focusing on sounds of interest over
irrelevant, background sounds is often considered in terms of cortical mechanisms …

The mammalian cochlea receives feedback from the brainstem medial olivocochlear (MOC)
efferents, whose putative 'antimasking'function is to adjust cochlear amplification and …

Sensory systems constantly adapt their responses to the current environment. In hearing,
adaptation may facilitate communication in noisy settings, a benefit frequently (but …

The cortical mechanisms underlying human speech perception in acoustically adverse
conditions remain largely unknown. Besides distortions from external sources, degradation …

The medial olivocochlear (MOC) bundle reduces the gain of the cochlear amplifier through
reflexive activation by sound. Physiological results indicate that MOC-induced reduction in …

Perceiving speech-in-noise (SIN) demands precise neural coding between brainstem and
cortical levels of the hearing system. Attentional processes can then select and prioritize task …

People with normal hearing thresholds can nonetheless have difficulty with understanding
speech in noisy backgrounds. The origins of such supra-threshold hearing deficits remain …

Human listeners are able to listen to one voice in the midst of other conversations and
background noise. Although the neural mechanisms for this process are not well …

One of the putative functions of the medial olivocochlear (MOC) system is to enhance signal
detection in noise. The objective of this study was to elucidate the role of the MOC system in …

Feedback networks in the brain regulate downstream auditory function as peripheral as the
cochlea. However, the upstream neural consequences of this peripheral regulation are less …
