WebSep 26, 2024 · Pallium in Birds’ Forebrain Contain High Cognitive Abilities. When researchers used 3D polarized light imaging to analyze the brains of three homing pigeons, they found a region in the forebrain called the pallium, which has fibers organized similar to those in mammals’ cortexes. WebNov 17, 2024 · In particular, birds prove to be exceedingly smart and can solve tasks that will challenge children. The cognitive abilities of birds are due to their large pallium, the part of the bird brain that is considered homologous to the mammalian neocortex. However, in contrast to the neocortex, the bird pallium is not arranged in layers.
