Avian pallium

In the neuroanatomy of animals, an avian pallium is the dorsal telencephalon of a bird's brain. The subpallium is the ventral telencephalon.

The pallium of avian species tends to be relatively large, comprising ~75% of the telencephalic volume. Birds have a unique pallial structure known as the hyperpallium, once called the hyperstriatum. Evidence suggests the avian pallium's neuroarchitecture to be reminiscent of the mammalian cerebral cortex. The avian pallium has also been suggested to be an equivalent neural basis for consciousness.

A 2002 conference at Duke University (Avian Brain Nomenclature Consortium) established a standard nomenclature for describing the avian pallium as follows:
