Avian pallium

In the anatomy of animals, an avian pallium is the telencephalon of a bird's brain.

Pallium of avian species tend to have a larger paleoencephalon in proportion to neopallium as compared to phylogenetically younger species. Birds have a unique paleoencephallar structure known as the hyperpallium, also called the hyperstriatum.

A 2003 conference established a standard nomenclature for describing the avian pallium as follows:

Neopallium
- pyriform cortex, olfactory bulb
- hippocampus
- corticoid area
Paleopallium
- hyperpallium
  - accessorium
  - intercalatum
  - densocellulare
- mesopallium
  - dorsale
  - ventrale
- nidopallium
  - entopallium
  - basorostralis
- arcopallium
- amygdaloid complex
  - posterior amygdala
Subpallium
- striatum
  - pateral
  - medial
- globus pallidus, ventral pallidum
- amygdaloid complex
  - nucleus taeniae
