ResumenThe results of recent studies investigating the connections and chemoarchitecture of the basal forebrain of amphibians provide strong evidence that tetrapod vertebrates share a common pattern of basal ganglia organization. This pattern includes the existence of dorsal and ventral striatopallidal systems, reciprocal connections between the striatopallidal complex and the diencephalic and mesencephalic basal plate (striato-nigral and nigro-striatal projections), and descending pathways from the striatopallidal system to the midbrain tectum and reticular formation. The connectional similarities are parallelled by similarities in the distribution of chemical markers of striatal and pallidal structures such as dopamine, substance P and enkephalin. Moreover, studies of development and expression of homeobox genes have given further support to the notion that both amniotic and anamniotic tetrapods have a common pattern of basal ganglia organization. A new nomenclature of basal forebrain structures in amphibians is proposed which reflects our current understanding of basal ganglia organization in this class of vertebrates.
