| Sumario: | 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. |
