比较了啮齿动物幼鼠、小鼠、大鼠、叙利亚仓鼠、田鼠和蒙古沙鼠的超声发声(USV)，作为抗惊恐药物筛选试验的基础研究。用实时频谱分析仪(RTS)采集低温条件下与母亲分离的幼鼠的USV，并用Signal软件将其转换成频谱和功率谱。啮齿动物幼鼠发出的紫外线波具有一定的特征，表现出种属特异性。我们认为这种物种特异性可能是由于幼鼠呼吸道的解剖结构和呼吸模式的差异所致。
Ultrasonic vocalizations (USVs) emitted by rodent pups, mouse, rat, Syrian hamster, vole, and Mongolian gerbil, were compared as a basic study for a screening test of anti-panic drugs. USVs of rodent pups, separated from their mother under a low temperature condition, were collected by Real-Time Spectrogram (RTS) apparatus, and transformed into spectrograms and power spectra by SIGNAL software. Waveforms of USVs emitted by the rodent pups showed several characteristic features, and species specificity of USVs was shown. We think that the species specificity might be due to differences of the anatomical structures in the respiratory tract and respiratory patterns in rodent pups.
