In the anatomy 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.
A 2002 conference at Duke University established a standard nomenclature for describing the avian pallium as follows:
- Pallium
- pyriform cortex
- olfactory bulb
- hippocampus
- corticoid area
- hyperpallium
- apicale
- intercalatum
- densocellulare
- mesopallium
- dorsale
- ventrale
- nidopallium
- field L2
- entopallium
- basorostralis
- arcopallium
- amygdaloid complex
- posterior amygdala
- nucleus taeniae
- Subpallium
- striatum
- lateral
- medial
- pallidum
- globus pallidus or dorsal pallidum
- ventral pallidum
- striatum
