✦ Synopsis

Adult zebra finches can produce lesioned birds than for intact birds. Discrimination normal song in the absence of Area X, lMAN, or DLM, between conspecific songs in general also took longer nuclei that constitute the anterior forebrain pathway of songbirds. Here, we address whether lesions involvin the lesioned birds, but missed significance level. ing Area X and lMAN affect adult male zebra finches' Birds with control lesions medial to Area X did not ability to discriminate between conspecific or heterosshow any differences from intact animals. Our results pecific songs. Intact birds and lesioned birds were suggest that an intact anterior forebrain pathway is trained on an operant GO/NOGO conditioning paranot required to discriminate between heterospecific digm to discriminate between hetero-or conspecific songs. In contrast, Area X and lMAN contribute to a songs. Both lesioned and intact birds were able to male zebra finch's ability to discriminate between its learn all discriminations.
