In zebra finches males, but not females, respond to gonadal androgens with the production of a stereotyped courtship song. Corresponding to this dimorphism in hormone sensitivity, two song-related neural regions, magnocellular nucleus of the anterior neostriatum (MAN) and hyperstriatum ventralis pars caudalis (HVc), have more cells that accumulate androgens in males than in females. The early hormonal environment establishes these sex differences in the brain and behavior such that females… CONTINUE READING
