Recent studies on the phyletic distribution of the habenular asymmetry in Vertebrates suggest that the right asymmetry is an ancient character in Agnatha and Ganoida while Amphibians and Reptiles inderwent a change from Chondrichthyes appears as a derivate character. Our observations show a very reduced asymmetry of the habenulae and of the fibers connecting them to the interpeduncular nucleus of the mesencephalus.

Abstract
Recent studies on the phyletic distribution of the habenular asymmetry in Vertebrates suggest that the right asymmetry is an ancient character in Agnatha and Ganoida while Amphibians and Reptiles inderwent a change from Chondrichthyes appears as a derivate character. Our observations show a very reduced asymmetry of the habenulae and of the fibers connecting them to the interpeduncular nucleus of the mesencephalus.File in questo prodotto:
