Cover legend: An in vivo image of the inner ear in a transgenic zebrafish embryo expressing green fluorescent protein in VIIIth ganglion neurons. Orange-colored cells are anterior macular hair cells labeled with a fluorescent dye, FM1-43; their basal membranes are contacted by peripheral axons of VIIIth ganglion neurons. For more information, see the article by Tanimoto et al. in this issue (pages 2762–2767).
