Study of the neural basis of the critical period for vocal learning by comparison between Bengalese finch and common marmoset

我们证实，社会隔离造成孟加拉雀的歌曲学习的关键期延长。利用cDNA微阵列技术，通过比较社会隔离和正常饲养的孟加拉雀幼雀，可以找到与鸣唱学习关键期相关的候选基因。普通狨猴脑中可塑性相关基因的表达模式与孟加拉雀脑中的相似。

We confirmed that the social isolation caused elongation of the critical period for song learning in Bengalese finch. We could find the candidate genes related to the critical period for song learning in the Bengalese finch brain by comparison between socially isolated juvenile and normal rearing juvenile by using cDNAmicroarray. The expression patterns of some plasticity-related genes in the common marmoset brain were similar to that of Bengalese finch brain.
