High Frequency Peaks of Auditory Sensitivity in Mice Found by a New Audiometric Test: A Preliminary Report
Department of Life Sciences, Polytechnic of Central London London W.I., England
The auditory sensitivity of adult mice has been investigated using a method that has not been previously described. This method involves recording the electromyogram (EMC) from the post-auricular muscles in response to tonal stimuli. The preliminary results presented here show a secondary, high-frequency peak of sensitivity in the audiogram, which approximately corresponds to the frequency of sound emitted by that species; this confirms the findings of previous workers. The advantages and disadvantages of using the post-auricular EMG response as a measure of auditory sensitivity are briefly discussed in comparison with other behavioral and physiological methods.
