Expression of several genes in the central extended amygdala and some surrounding areas of chicken at E18–E19.

aGradiental expression, from [rostral]low to [caudal]high.
bIslet1 expression is seen in a compact periventricular area of BSTLdm (adjacent to the Nkx2.1-rich ventricular zone).
cThe perioval zone is subdivided into a dorsal part rich in pENK and a ventral part poor in pENK.
dCRFR2 shows a stronger expression in the lateral part of the striatum, StC, and pINP.
eAt this age, CRFR2 is only expressed at caudoventral levels of Ceov.
