Auditory Processing and Perception of Ultrasounds in House Mice
Housemice have a vocal repertoire of 8 different call types, at least 4 of these are used in intraspecific communication (Ehret, 1975; Haack et al., 1982; Whitney and Nyby, 1982). There is always interindividual variability among calls of one type; therefore, the receiver of the calls must generalize across this variability in order to identify a call type, and to discriminate a particular call from others and from the acoustic background. The present paper deals with ultrasound perception by house mice. This example of call perception clearly demonstrates the abilities of the animals to generalize, to identify and to discriminate species-specific calls. The key-stimulus configuration in the frequency domain for ultrasound perception is described and then the physiological basis for why and how the mouse is able to perceive the ultrasonic calls is discussed.
