Cover legend: Confocal image of the saccular epithelium and nerve of a 2-d-old rat; the utricular epithelium is partly visible from the side at the top left. Overlying structures have been removed to expose the apical surfaces of the epithelia. The vestibular nerve fibers are labeled with anti-βIII tubulin (red), hair bundles are labeled with phalloidin (green), and type II hair cells and striolar afferents are labeled with anti-calretinin (blue). For details, see the article by Songer and Eatock (pages 3706–3724).
