Abstract

Rats are able to produce ultrasonic vocalizations (USVs). Such USVs are an important component of the rat social behavior repertoire and serve distinct communicative functions as socio-affective signals. Depending on the emotional valence of the situation, juvenile and adult rats utter (1) aversive 22-kHz USVs conveying an appeasing and/or alarming function; or (2) appetitive 50-kHz USVs, which act as social contact calls, amongst others. A 50-kHz USV radial maze playback paradigm that allows assessment of the behavioral responses displayed by the recipients in a highly standardized manner has been developed. In this newly developed paradigm, a rat is exposed individually to playback of natural 50-kHz USVs and appropriate acoustic control stimuli using an acoustic presentation system for ultrasound. By this means, it has been consistently shown that 50-kHz USVs lead to social approach behavior in the recipient, supporting the notion that they serve an affiliative function as social contact calls. © 2016 by John Wiley & Sons, Inc.

通过超声发声回放研究大鼠的社会情感交流

老鼠能够发出超声波(usv)。这些usv是大鼠社会行为库的重要组成部分，作为社会情感信号具有独特的交流功能。根据情况的情绪效价，幼鼠和成年鼠发出(1)令人厌恶的22 khz usv，传达安抚和/或警报功能;或(2)食欲50 khz的usv，作为社交呼叫等。一个50千赫USV径向迷宫回放范式，允许以高度标准化的方式评估接受者的行为反应。在这个新开发的范例中，使用超声声学呈现系统，将大鼠单独暴露于自然50 khz usv和适当的声学控制刺激中。通过这种方式，已经有一致的证据表明，50 khz的usv会导致接受者的社会接近行为，这支持了它们作为社会联系呼叫具有附属功能的观点。©2016 by John Wiley &儿子,Inc。
