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.
The bird brain is divided into a number of sections, each with a different function. The cerebrum or telencephalon is divided into two hemispheres, and controls higher functions. The telencephalon is dominated by a large pallium, which corresponds to the mammalian cerebral cortex and is responsible for the cognitive functions of birds. The ...

The avian nidopallium is an area of the cortical telencephalon of the avian forebrain, and is itself subdivided into smaller regions as a result of further functional localisation. It has been apportioned along the rostrocaudal (anteroposterior) axis into three hypothetical segments: the rostral, intermediate and caudal nidopallium. [ 1 ]
The cerebrum (pl.: cerebra), telencephalon or endbrain [1] is the largest part of the brain, ... Birds and fish have a dorsal telencephalon, like all vertebrates, but ...
The following table gives information on the number of neurons estimated to be in the sensory-associative structure: the cerebral cortex (aka pallium) for mammals, the dorsal ventricular ridge ("DVR" or "hypopallium") of the pallium for birds, and the corpora pedunculata ("mushroom bodies") for insects.
The general layout or body plan of the pallium is already clearly defined in animals with relatively simple brains, including lampreys, sharks and amphibians. In teleost fish, reptiles, birds, and mammals, the pallial architecture is greatly modified (sharply diverging in fish), with differential growth and specialization of diverse sectors of the conserved pallial Bauplan.
