Abstract
The male zebra finch sings, whereas the female does not. This behavioral dimorphism is correlated with the presence of morphological sex differences within the neural substrate that mediates this behavior, the song system. When a female chick is exposed to 17beta-estradiol her song system is subsequently masculinized. Either testosterone or 5alpha-dihydrotestosterone may then induce such a female to sing when an adult.
摘要
雄斑马雀会唱歌，而雌斑马雀则不会。这种行为的二态性与介导这种行为的神经基质（即歌唱系统）内存在形态性别差异有关。当一只雌性雏鸟暴露于 17β-雌二醇中时，其歌唱系统随后会被雄性化。当成年后，无论是睾丸酮还是 5α-二氢睾丸酮都可能诱导这样的雌性开始唱歌。
