Neonatal rat ultrasound repetition rates were monitored in response to 6 odor cues, including 1 novel, 2 predator, and 3 conspecific olfactory stimuli. Contrary to predictions of previous studies, predator odor did not elicit consistently low call rates. A significant difference was detected between litters tested with the same odor cue for the foreign and predator odor treatments. Odor was the only significant effect to explain differences in neonatal ultrasonic responses to conspecific odor treatments. Call rates recorded for the novel lactating female odor were significantly greater than those for the home bedding and adult male odors. Odors associated with the home cage or with an adult male elicited low call rates.
监测新生大鼠对6种气味线索的超声重复率,其中包括1种新异气味、2种捕食者气味和3种同种个体的嗅觉刺激。与先前研究的预测相反,捕食者气味并未始终引发较低的鸣叫率。在用相同气味线索进行外来气味和捕食者气味处理的不同窝幼崽之间检测到显著差异。气味是解释新生大鼠对同种个体气味处理的超声反应差异的唯一显著因素。记录到的对新异泌乳雌性气味的鸣叫率显著高于对窝垫和成年雄性气味的鸣叫率。与饲养笼或成年雄性相关的气味引发较低的鸣叫率。
