Abstract

Aboitiz and colleagues propose that the tectorotundal pathway of birds and reptiles is homologous not to the mammalian colliculopulvinar system but to the posterior complex/intralaminar nuclei. However, as outlined below, a large amount of strong evidence points to a homology of the tectorotundal and the colliculopulvinar system. This makes it likely that DVR and isocortex might be in part homologous
