What is "nidopallium"

n. A region of the avian brain, used mostly for some types of executive functions but also for other higher cognitive tasks.

The nidopallium, meaning nested pallium, is the region of the avian brain that is used mostly for some types of executive functions but also for other higher cognitive tasks. The region was renamed to nidopallium in 2002 during the Avian Brain Nomenclature Consortium because the prior name, neostriatum, suggested that the region was used for more primitive functions as the neostriatum in mammalian brains is sub-cortical.
