Abstract

The ultrasonic vocalization (USV) response of the isolated infant rat is a promising model for studying the neurobiology of an early anxiety state, and potentiation of the USV response after brief maternal encounters is a newly discovered behavioral regulator of this state. Using experimental variations in the contexts and patterns of maternal behavior during pup encounters and manual simulations of maternal behavior, we have identified several specific mother-pup interactions that cause potentiation. When one of these, pup carrying, was manually simulated, potentiation followed only if a characteristic postural transport response had been fully expressed by the pup. These behavioral mechanisms and other data suggest hypotheses for the development and adaptive role of maternal potentiation.

摘要

隔离幼鼠的超声发声（USV）反应是研究早期焦虑状态神经生物学的一个有前景的模型，短暂母婴接触后USV反应的增强是该状态新发现的行为调节因素。通过改变幼崽接触期间母性行为的背景和模式以及人工模拟母性行为，我们确定了几种导致反应增强的特定母婴互动。当人工模拟其中一种行为——携带幼崽时，只有在幼崽充分表现出特征性的姿势转移反应后，反应才会增强。这些行为机制和其他数据为母性增强作用的发展和适应性作用提出了假设。
