[Evaluation of the interrelations among auditory potential parameters by means of the technic of correlation-regression analysis]. / otsenka vzaimosviazi parametrov slukhovykh potentsialov s pomoshch'iu metoda korreliatsionno-regressionnogo analiza.

The characteristics (amplitude, latency) of two types of evoked potentials, action potential of the 8th nerve recorded at the cochlea round window and sonomotor evoked potential recorded from the postauricular region and the back of the guinea pigs were studied in response to sound stimulation. The degree and type of interrelation between the parameters of the auditory evoked potentials were established employing the method of correlation-regression analysis. A close linear dependence was established for amplitude values ( r = 0.93) of the action potential and the sonomotor potential irrespective of the recording site of the latter. The similar dependence (r = 0.91) was established when analysing the latency of the action potential and the evoked sonomotor potential, if the latter was in the postauricular region. The performed mathematical simulation permitted justifying the correction of disturbed functions of the auditory system.

[Electrical responses recorded from the round window of the cat cochlea]. / Issledovanie élektricheskikh otvetov, otvodimykh ot kruglogo okna ulitki koshki.

The parameters of the cochlear round window responses to stimulation by acoustic clicks of different intensity, polarity and frequency were studied in experiments on anesthetized cats. The intensity function reflecting the dependence of the amplitude of potential change upon the level of stimulating click included two parts differing in slope. The dependence of the electric responses on the stimulus intensity and frequency was also studied. A specific form of the reaction was found in some cases. The study of all these parameters gives us some reasons to make a conclusion on the function of the auditory nerve.
