...Kei Yamamoto; Pierre Estienne; Solal Bloch Background: Comparative neuroanatomists have long sought to determine which part of the pallium in nonmammals is homologous to the mammalian neocortex. A number of similar connectivity patterns across species have led to the idea that the basic...

...-telencephalic). In the last two decades, the tetrapartite pallial paradigm defined the pallial portion of the amygdala as a derivative of the lateroventral pallium. However, the pallial conception is currently being reanalyzed and one of these new proposals is to consider the mouse pallial amygdala as a radial...

Thus, at dorsomedial telencephalic portions a region comparable to the cortical hem was defined in Xenopus based...

...Georg F. Striedter; R. Glenn Northcutt Comparative neurobiologists have long wondered when and how the dorsal pallium (e.g., mammalian neocortex) evolved. For the last 50 years, the most widely accepted answer has been that this structure was already present in the earliest vertebrates...

Here, we show that pallium areas associated with domain-general cognition represent a large fraction of the entire brain, are disproportionally larger in large-brained birds and accurately predict variation in the whole brain when...

...Mark R. Braford, Jr. Compared to land vertebrates and the other fishes, the basal ray-finned fishes and teleosts have morphologically unusual forebrains.
