Auditory thalamus responses to guinea-pig vocalizations: A comparison between rat and guinea-pig

Résumé

Although neuronal responses to species-specific vocalizations have long been described, very few between-species comparisons have been made. In a previous study, a differential representation of species-specific vocalizations was found in the auditory cortex (ACx): marmoset ACx neurons responded more, and more selectively, to marmoset calls than did cat ACx neurons [Wang, X., Kadia, S.C., 2001. Differential representation of species-specific primate vocalizations in the auditory cortices of marmoset and cat. J. Neurophysiol. 86, 2616-2620]. The present study analyzed responses of guinea-pig and rat auditory thalamus neurons to four well-defined guinea-pig vocalizations. Neurons of guinea-pigs (n = 96) and rats (n = 87) displayed similar response strength to guinea-pig vocalizations, and did not exhibit a preference for the natural over the time-reversed version of the calls in both species. This difference with the study by Wang and Kadia might suggest that, in mammals, the selectivity for the natural version of species-specific vocalizations is prominent only at the cortical level.
