In male zebra finches, song learning is accompanied by the addition of new neurons to Area X, a nucleus necessary for normal song development. We examined whether Area X neurons born after 15 days post-hatch are recruited into the efferent pathway from Area X to the dorsolateral nucleus of the medial anterior thalamus (DLM). Our data suggest that the majority of these new Area X neurons are interneurons and that DLM-projecting neurons are incorporated into Area X prior to song learning.
在雄性斑胸草雀中，鸣叫学习伴随着新神经元添加到X区，X区是正常鸣叫发育所必需的一个核团。我们研究了孵化后15天出生的X区神经元是否被招募到从X区到丘脑前内侧背外侧核（DLM）的传出通路中。我们的数据表明，这些新的X区神经元大多数是中间神经元，并且投射到DLM的神经元在鸣叫学习之前就已并入X区。
