Abstract

Based on anatomical and functional data, the habenula-a phylogenetically old brain structure present in all vertebrates-takes part in the integration of limbic, sensory, and basal ganglia information to guide effective response strategies appropriate to environmental conditions. In the present study, we investigated the connections of the habenular nuclei of the oriental fire-bellied toad, Bombina orientalis, and compared them with published data from lampreys, chondrichthyes, teleosts, reptiles, birds, and mammals. During phylogenetic development, the primordial habenula circuitry underwent various evolutionary adaptations and in the tetrapod line, the circuit complexity increased. The habenula circuitry of anuran amphibians, decedents of the first land-living tetrapods, seem to exhibit a mix of ancient as well as modern features. The anuran medial and lateral habenula homologs receive differential input from the septum, nucleus of the diagonal band of Broca, preoptic area, hypothalamus, rostral pallium, nucleus accumbens, ventral pallidum, and bed nucleus of the stria terminalis. Additional input arises from a border region in the ventral prethalamus, here discussed as a putative homolog of the entopeduncular nucleus of rodents. The habenular subnuclei also differentially innervate the interpeduncular nucleus, raphe nuclei, substantia nigra pars compacta and ventral tegmental area homologs, superficial mamillary area, laterodorsal tegmental nucleus, locus coeruleus, inferior and superior colliculus homologs, hypothalamus, preoptic area, septum, nucleus of the diagonal band of Broca, and main olfactory bulb. It seems likely that the main connectivity between the habenula and the basal ganglia, limbic, and sensory systems was already present in the common tetrapod ancestor.
