Analogous brain regions in zebra finch and mammals

Zebra finch nuclei		Mammalian brain region
abbreviation	Full name
HVC (letter-based name)	Formerly High Vocal Center	Dorsal telencephalon*
Area X	Area X	Basal Ganglia
DLM	DorsoLateral Medial nucleus of the thalamus	Thalamus
LMAN	Lateral Magnocellular nucleus of Anterior Nidopallium	Dorsal telencephalon*
RA	Robust nucleus of the Arcopallium	Unique to avians but best described as vocal premotor cortex, similar to (but distinct from) the somatic telencephalon

^*Derived from the telencephalic pallial sector of the developing brain (mammalian pallial derivatives are the neocortex, amygdala, and claustrum) [(Reiner et al., 2004) and Reiner et al., (2004)].
