在雌性哺乳动物发情周期的不同阶段，雌性哺乳动物的感知、母性动机和行为是如何变化的？在这里，我们显示的影响，动情周期阶段的感知的声学意义和母亲的行为在处女家鼠（小家鼠）在接触年轻的，他们共同照顾与母亲。周期性雌性在发情间期，发情前期，发情期或发情后期回应小鼠幼崽蠕动的呼吁和两个合成的呼叫模型时，他们在一个“护理”的立场对幼崽。独立的发情周期的阶段，处女女性的自然发声呼叫的反应率和自发的母性行为的比率约为母亲在相同的行为设置的一半。这表明，母性的动机处女女性一般是母亲的一半，但在发情周期相当恒定。在雌性的发情周期中，对呼唤模型的反应率发生变化。在动情间期和动情前期（而不是在动情期和动情后期），他们感知到的声音之间的差异，呼吁模型和回应不同的利率母性行为。在发情期，它们表现出母性行为的比率很高，并且更喜欢与自然叫声相似的叫声模式。在动情后期，对合成的呼叫模型的反应率很低，因此只有自然的呼叫（不是呼叫模型）才能以很高的速度释放母性行为。这些来自家鼠的行为数据显示出与女性月经周期期间的感知可塑性以及情绪和情绪依赖性反应的显著相似性。(C)2008年爱思唯尔公司All rights reserved.
How may perception, maternal motivation and behavior of female mammals change during different phases of their estrous cycle? Here, we show effects of estrous cycle phase on the perception of acoustic meaning and maternal behavior in virgin house mice (Mus musculus) during contact with young for which they were co-caring together with the mother. Cycling females in diestrus, proestrus, estrus or metestrus responded to mouse pup wriggling calls and two synthesized call models when they were in a "nursing" position on the pups. Independent of the phase of their estrous cycle, the virgin females' response rates to naturally vocalized calls and the rates of their spontaneous maternal behavior were about half of those of mothers in the same behavioral setting. This suggests that the maternal motivation of virgin females is generally half of that of mothers but rather constant during the estrous cycle. The response rates to the call models changed during the females' estrous cycles. During diestrus and proestrus (not in estrus and metestrus) they perceived acoustic differences between the call models and responded with different rates of maternal behavior. In estrus, they showed maternal behavior at a high rate and preferred the call models similar to the natural calls. In metestrus, response rates to the synthesized call models were low, so that only natural calls (not call models) released maternal behavior at a high rate. These behavioral data from house mice show remarkable similarities with perceptual plasticity and emotional and mood-dependent reactivity during the menstrual cycle in women. (C) 2008 Elsevier Inc.
