Developmental and seasonal changes in the production of androgens and estrogens seem to control sex-specific differentiation and seasonal changes in sexual behaviors such as singing of songbirds. These steroids affect the brain by binding to intracellular located receptors. Here we analyze whether the expression of androgen receptors (AR) and estrogen receptors (ER) is a limiting factor for differentiation of the vocal pattern and the vocal control system of zebra finches and canaries. AR and… CONTINUE READING
