Thepallium ofavian species tends to be relatively large, comprising ~75% of the telencephalic volume. Evidence suggests the avian pallium's neuroarchitecture to be reminiscent of themammaliancerebral cortex.[1] The avian pallium has also been suggested to be an equivalent neural basis forconsciousness.[2][3] Birds also have a unique pallial structure known as thehyperpallium, once called thehyperstriatum.
