[Dynamics of the harmonic components of the cochlear microphonic potential during acoustic overloading and exposure to ototoxic substances].
The 2nd and the 3rd harmonic components of microphonic potentials in the rabbit cochlear, under the influence of sound stimuli of different intensity, developed simultaneous and equal changes of their characteristics of the odd harmonic as well as of the basic tone. The even harmonic did not depend on the dynamic characteristics of the basic tone of microphonic potentials. The even harmonic developed its own specific changes. In separate experiments, the effects of sound overload, etacrine acid and streptomycin on the dynamic characteristics of the even harmonic, were studied.
