Variability of the influence of a visual task on the active micromechanical properties of the cochlea

The effect of a visual task on the active micromechanical properties of the cochlea studied by the evoked otoacoustic emissions (EOAEs) has been the subject of only one published study ( Brain Research, 44 (1988) 380–383). In order to examine the reliability of this effect, a similar study has been...

Zusammenfassung:	The effect of a visual task on the active micromechanical properties of the cochlea studied by the evoked otoacoustic emissions (EOAEs) has been the subject of only one published study ( Brain Research, 44 (1988) 380–383). In order to examine the reliability of this effect, a similar study has been run on 16 subjects. A significant decrease in EOAEs during a visual task was obtained for 3 subjects. The two subjects whose decrease was the most significant were tested again one month later and the same effect was found. This striking interindividual variability is discussed in terms of olivo-cochlear neuronal excitability.
