PRJDB3398 Gene expression analysis of vocal motor system in songbirds Research goal of this project belongs to two major parts using songbird brain samples. The first part is to identify genes that are differentially induced by singing during a critical period of vocal learning. The second part goal is to identify a set of genes that are regulated with allelic imbalance in song motor nuclei, HVC and RA.
