新生小鼠和所有新生啮齿动物一样，能够发出高频信号，特别是当它们被赶出巢穴时。此外，已知在这种情况下，在养母中诱导检索行为，这可能揭示近交系小鼠之间的稳定差异。由此产生的问题是，这些差异是否与幼仔信号传导率和/或这些品系的雌性感知它们的能力的差异有因果关系。为了提供对这个问题的见解，观察了8个近交系小鼠的行为：A/J，BALB/c，CBA/H，C57 BL/6，C57 Br，NZB和XLII。记录这些菌株中每种菌株的幼仔超声呼叫，并将其制成表格，这些超声呼叫在与回收试验相同的条件下发出。属于这些菌株的女性的听觉灵敏度测定记录在下丘的听觉诱发电位。分析这2个变量与这些品系雌性动物在检索试验3个变量上的评分的关系。研究结果表明，除了听觉线索的存在，其他因素必须考虑到描述不同菌株在检索性能的差异。这一结论已得到证实的结果，使用交叉培养程序。无法利用超声波信息的雌性小鼠可能会使用其他感觉通道。此外，能够感知超声波的雌性小鼠也可能能够在不同的情况下使用不同的感觉方式。
Newborn mice, like all newborn rodents, are able to emit high frequency signals, in particular when they are put out of the nest. Moreover, it is known that in this situation retrieving behaviors are induced in the foster mother, which are likely to reveal stable differences across inbred strains of mice. The question that arises is whether these differences are causally linked to differences in the pup rate of signalling and/or to the capacity of the females of these strains to perceive them. To provide insights into this question, the behavior of 8 inbred strains of mice was observed: A/J, BALB/c, CBA/H, C57BL/6, C57Br, NZB and XLII. Pup ultrasonic calls of each of these strains, emitted in the same conditions as a retrieving test, were recorded and tabulated. Auditory sensitivities of females belonging to these strains were determined by auditory evoked potentials recorded in the inferior colliculus. These 2 variables were analyzed in relation to scores of females of these strains on 3 variables of a retrieving test. Results show that the presence of other factors than auditory cues must be taken into account to describe differences across strains in retrieving performances. This conclusion has been confirmed by results obtained using cross-fostering procedure. Female mice unable to utilize ultrasonic information may use other sensory channels. Furthermore, female mice capable of perceiving ultrasounds may also be able to use different sensory modalities in different situations.
