Behavioral studies of the olivocochlear efferent system: learning to listen in noise.
BACKGROUND Olivocochlear (OC) neurons make up an efferent, descending auditory system that returns sound representations to the inner ear soon after they have entered the brain. Efferent inputs into the cochlea modulate outer hair cell activity to improve the neural encoding of auditory signals in background noise. Based on this physiological evidence, loss of efferent feedback is expected to d...
متن کاملStudy of the medial olivocochlear efferent system through otoacoustic emissions
The purpose of this study was to investigate the efferent medial olivocochlear system through the use of otoacoustic emissions and especially the modifications that occur at this level with age. The activity of outer hair cells (OHCs) (peripheral) and of the efferent medial olivocochlear (MOC) system (neural and central) was examined by means of distortion product otoacoustic emissions (DPOAEs)...
متن کاملOlivocochlear efferent suppression in classical musicians.
Suppression of transient-evoked otoacoustic emissions was recorded from 29 members of the Louisiana Philharmonic Orchestra and 28 non-musician control subjects matched for age and gender. Binaural broad band noise was used as the suppressor stimulus in a forward masking paradigm. Results showed musicians to have significantly more suppression than non-musicians for both the right and left ears....
متن کاملTop-Down Influences of the Medial Olivocochlear Efferent System in Speech Perception in Noise
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 speech perception in noise. In normal-hearing human listeners, we examined (1) the association between magnitude of MOC inhibition and speech-in-noise performance, and (2) the association between MOC inhibition...
متن کاملThe Efferent System or Olivocochlear Function Bundle – Fine Regulator and Protector of Hearing Perception
The efferent system of the ear possesses several distinct functions, in particular noise protection, mediation of selective attention and improvement of signal to noise ratio. It also supports adaptation and frequency selectivity by modification of the micromechanical properties of outer hair cells. There are many differences in anatomy and physiology between the medial and lateral olivocochlea...
