[Mouse auditory sensitivity as measured by averaged evoked potentials].

The audition of four strains of mice was determined with summated auditory evoked potentials at the inferior colliculus level. One of these strains was completely deaf. For the 3 others a specific auditory sensitivity was found with statistically different thresholds. But, for these, the best sensitivity is around 16 kHz. Two of them show a flattening of the curve between 32 and 64 kHz. This range corresponds to the ultrasounds emitted by the pups.
