Abstract
A defining feature of the mammalian auditory system is the extensive processing of sound information in numerous ultrafast and temporally precise circuits in the hindbrain. By exploiting the experimental advantages of mouse genetics, recent years have witnessed an impressive advance in our understanding of developmental mechanisms involved in the formation and refinement of these circuits. Here, we will summarize the progress made in four major fields: the dissection of the rhombomeric origins of auditory hindbrain nuclei; the molecular repertoire involved in circuit formation such as Hox transcription factors and the Eph-ephrin signaling system; the timeline of functional circuit assembly; and the critical role of spontaneous activity for circuit refinement. In total, this information provides a solid framework for further exploration of the factors shaping auditory hindbrain circuits and their specializations. A comprehensive understanding of the developmental pathways and instructive factors will also offer important clues to the causes and consequences of hearing-loss related disorders, which represent the most common sensory impairment in humans.
