## Abstract To assess which hormones are capable of masculinizing the neural song system of zebra finch hatchlings, we implanted female hatchlings with estrogen (estradiol [E2], 75 ฮผg, __n__ = 9), testosterone (T, 75โ88 ฮผg, __n__ = 13), androstenedione (AE, 75 ฮผg, __n__ = 7), progesterone (P, 117 ฮผ
The zebra finch telencephalon exhibits rapid and substantial development in the first few weeks after hatching. In parallel, the rate of estradiol synthesis is very high in the zebra finch forebrain, and estradiol can have potent neurotrophic effects in specific telencephalic regions, including thos
