Research Abstract

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.
