Singing-related activity in anterior forebrain of male zebra finches reflects courtship motivation for target females.

A critical function of singing by male songbirds is to attract a female mate. Previous studies have suggested that the anterior forebrain system is involved in this courtship behavior. Neural activity in this system, including the striatal Area X, is strikingly dependent on the function of male sing...
