Here, we show that rats can recognize the identity of the USV emitter since they choose to preferentially self-administer playback of 50-kHz USVs emitted by a stranger rat over those of their cagemate. In a second experiment, we show that only stranger, but not familiar, 50-kHz USVs reduce cocaine self-administration. Finally, to study the neurobiological substrate of these processes, we have shown that subthalamic nucleus (STN)-lesioned rats did not lever press much for any USV playback, whatever their emotional valence, nor did they seem able to differentiate familiar from stranger peer. Advocating for the existence of a vocal signature in rats, these results highlight the importance of ultrasonic communication in the socio-affective influence of behaviour, such as the influence of proximal social factors on drug consumption and confirm the role of the STN on this influence.<\/jats:p>","DOI":"10.1098\/rspb.2021.2260","type":"journal-article","created":{"date-parts":[[2021,12,15]],"date-time":"2021-12-15T00:05:58Z","timestamp":1639526758000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["Evidence for a vocal signature in the rat and its reinforcing effects: a key role for the subthalamic nucleus"],"prefix":"10.1098","volume":"288","author":[{"given":"Cassandre","family":"Vielle","sequence":"first","affiliation":[{"name":"Institut de Neurosciences de la Timone, UMR 7289 CNRS and Aix-Marseille Universit\u00e9, 27 Boulevard Jean Moulin, Marseille 13005, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Montanari","sequence":"additional","affiliation":[{"name":"Institut de Neurosciences de la Timone, UMR 7289 CNRS and Aix-Marseille Universit\u00e9, 27 Boulevard Jean Moulin, Marseille 13005, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yann","family":"Pelloux","sequence":"additional","affiliation":[{"name":"Institut de Neurosciences de la Timone, UMR 7289 CNRS and Aix-Marseille Universit\u00e9, 27 Boulevard Jean Moulin, Marseille 13005, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4368-652X","authenticated-orcid":true,"given":"Christelle","family":"Baunez","sequence":"additional","affiliation":[{"name":"Institut de Neurosciences de la Timone, UMR 7289 CNRS and Aix-Marseille Universit\u00e9, 27 Boulevard Jean Moulin, Marseille 13005, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2021,12,15]]},"reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/scientificamerican0167-78"},{"key":"e_1_3_6_3_2","first-page":"255","article-title":"Social mechanisms and social structure in rats and mice","volume":"19","author":"Lund M","year":"1975","unstructured":"Lund M. 1975 Social mechanisms and social structure in rats and mice.
