| description | This article develops with a comparative approach a comprehensive and updated review of studies of aversive learning in amphibians. Most of them used electric shock as aversive stimulus, resulting in inconsistent or negative results. Recent research showed that another class of stimuli (saline solutions highly concentrated or warm water) has been more efficient to produce steady changes in behavior. Some neurophysiological aspects of aversive and fear learning are also discussed. While comparative data from neurophysiological studies in fish is available, there are no references on functional information on the neural basis of aversive learning in amphibians. However, it is known in amphibian homologous brain areas to the mammalian structures shown to be involved with such learning (especially the amygdala), opening the way to address the study of this question in the future. |

El presente artículo desarrolla con un enfoque comparado una revisión completa y actualizada de los estudios de aprendizaje aversivo en anfibios. La mayoría de ellos utilizaron como estímulo aversivo descargas eléctricas, obteniéndose resultados inconsistentes o negativos. Las investigaciones más recientes mostraron que otra clase de estímulos (soluciones salinas de alta concentración, o aumento de la temperatura del agua) han resultado ser más eficientes para producir modificaciones estables en el comportamiento. Se analizan también algunos aspectos neurofisiológicos relacionados con el aprendizaje aversivo y los miedos aprendidos. Si bien se cuenta con datos comparativos de estudios neurofisiológicos en peces, aún no existen referencias con información funcional sobre las bases neurales del aprendizaje aversivo en anfibios. Sin embargo, sí se conoce en anfibios las regiones cerebrales homólogas a las estructuras que en mamíferos mostraron estar implicadas con dicho aprendizaje (especialmente la amígdala), abriendo así el camino para abordar en el futuro el estudio de esta cuestión.
