説明
The purpose of these experiments was to study the exciting phases of the auditory nerve against cochlear microphonics. Whole nerve action potential (N1) amplitudes to the high frequency test tones under continuous low frequency (50Hz) acoustic and electric bias stimulation were compared to N1 amplitude to the test tone only. The numbers of action potential (AP) from the single auditory nerve fibers were recorded to 50Hz triangle and sine wave acoustic stimulation.<br>Following results were obtained. 1) There was no doubt that CM played very important role about the mechanism of AP discharge. The exciting phases were different almost 180 degrees under between acoustic and electric stimulation. It was agree with the mechanoelectrical theory. 2) The responses were noticed to the velocity and displacement components of the basilar memblane movement in the all of single auditory nerve fibeors. 3) The exciting phase was the zero-crossing point from positive to negative of CM under acoustic stimulation and zero-crossing point from negative to positive of CM under electric stimulation in the N1 experiments 4) The exciting phases moved systematically and gradually depending on the characteristic frequencies (CF) of single auditory nerve fibers. Some of the low CF fibers showed exciting phases near the positive peaks of CM and some of the high CF fibers showed exciting phases near the negative peaks of CM and maximum current peaks through the hair cells. 5) The results in 2), 3) and 4) were not able to explained by means of only the mechanoelectrical theory. Therefore, there was a possibility to think about the electrical interaction between the inner and outer hair cells.
