Avian pallium explained

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.^[1] The avian pallium has also been suggested to be an equivalent neural basis for consciousness.^{[2] [3]}

A 2002 conference at Duke University (Avian Brain Nomenclature Consortium) established a standard nomenclature for describing the avian pallium as follows:^{[4] [5] [6] [7]}

• 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
