Amphibians Bufo arenarum Intrumental conditioning Learning Medial pallium In the present paper, amphibian behavioral mechanisms literature is revised. Very little is known about learning processes in amphibians, and even less about brain-learning relations. We recently began a systematic study of instrumental learning in the toad Bufo arenarum within a comparative framework. Several learning phenomena common to a wide variety of vertebrates were observed, such as acquisition under massed and spaced training conditions, extinction, spontaneous recovery, the reward-following effect, and the magnitude of reinforcement acquisition effect. In addition, we began the analysis of the effects of lesions in the medial pallium (postulated to be the homologous of the mammalian hippocampus) on learning. The lesion of the medial pallium showed no effect neither on acquisition nor in the amount of water uptake during acquisition. Lesions significantly retarded extinction of a water-reinforcement instrumental response in a runway training situation. These data suggest that the medial pallium of toads plays a role in response inhibition. The results of our experiments in the toad Bufo arenarum contribute to the limited information available on learning in amphibians.
