[Effect of attention on audition. Contribution of the study of the olivocochlear efferent system].

It is possible by studying the Evoked Otoacoustic Emissions (EOAEs) to detect an effect of selective attention on the cochlea. The authors present the main data of the literature and the results of their works. They show an effect of visual attention as well as auditory attention on the EOAEs. This effect is not the same whether attention is visual or auditory. There is a result of selective attention as early as the cochlear level.
