Brain and muscle are sexually differentiated tissues in which masculinization is controlled by the secretion of androgens from the testes. Sensitivity to androgen is conferred by the expression of an intracellular protein, the androgen receptor. A central problem of sexual differentiation is thus to understand the cellular and molecular basis of androgen action. We do not understand how hormone occupancy of a receptor translates into an alteration in the developmental program of the target cell. Our studies on sexual differentiation of brain and muscle in Xenopus laevis are designed to explore the molecular basis of androgen induced sexual differentiation by examining how this hormone controls the masculinization of brain and muscle targets.Our approach to this problem has focused on a highly androgen sensitive, sexually dimorphic neuromuscular system: laryngeal muscles and motor neurons of the clawed frog, Xenopus laevis. We have been studying sex differences at a synapse, the laryngeal neuromuscular junction, which mediates sexually dimorphic vocal behavior in Xenopus laevis frogs.

Abstract This article examines iconic American deafblind writer Helen Keller's entræ#169;e into musical culture, culminating in her studies with voice teacher Charles A. White. In 1909, Keller began weekly lessons with White, who deepened her understanding of breathing and vocal production. Keller routinely made the acquaintance of opera singers in the 1910s and the 1920s, including sopranos Georgette Leblanc and Minnie Saltzman-Stevens, and tenor Enrico Caruso. Guided by the cultural logic of oralism, Keller nurtured a lively interest in music throughout her life. Although a voice-centred world-view enhanced Keller's cultural standing among hearing Americans, it did little to promote the growth of a shared identity rooted in deaf or deafblind experience. The subsequent growth of Deaf culture challenges us to reconsider the limits of Keller's musical practices and to question anew her belief in the extraordinary power of the human voice.
