矿化皮质激素受体是皮质类固醇如皮质酮或醛固酮的受体。在此之前，我们发现矿化皮质激素受体在鸣禽——孟加拉雀（Lonchura striatavar）的鸣叫核中高度表达。有明显)。为了研究矿物皮质激素受体表达与鸟类发声学习之间的关系，我们分析了另一种发声学习者虎皮鹦鹉（Melopsittacus undulatus）和非发声学习者鹌鹑（Coturnix japonica）和环鸽（Streptopelia capicola）大脑中矿物皮质激素受体的表达。矿化皮质激素受体在虎皮鹦鹉和孟加拉雀中有声控区相关的表达，而在非发声学习者的端脑中没有矿化皮质激素受体的表达。因此，这些结果表明，矿物皮质激素受体可能在鹦鹉作为鸣禽的声音发育中起作用，并且矿物皮质激素受体的获得表达参与了鸟类声音学习的进化。
Mineralocorticoid receptor is the receptor for corticosteroids such as corticosterone or aldosterone. Previously, we found that mineralocorticoid receptor was highly expressed in song nuclei of a songbird, Bengalese finch (Lonchura striatavar. domestica). Here, to examine the relationship between mineralocorticoid receptor expression and avian vocal learning, we analyzed mineralocorticoid receptor expression in the developing brain of another vocal learner, budgerigar (Melopsittacus undulatus) and non‐vocal learners, quail (Coturnix japonica) and ring dove (Streptopelia capicola). Mineralocorticoid receptor showed vocal control area‐related expressions in budgerigars as Bengalese finches, whereas no such mineralocorticoid receptor expressions were seen in the telencephalon of non‐vocal learners. Thus, these results suggest the possibility that mineralocorticoid receptor plays a role in vocal development of parrots as songbirds and that the acquisition of mineralocorticoid receptor expression is involved in the evolution of avian vocal learning.
