Cover legend: Cochlear inner hair cell from an adult mouse, viewed as a three-dimensional reconstruction from a whole mount confocal stack. The inner hair cell is labeled with Myo7a (grey), ribbon synapses and hair cell nuclei are labeled with CtBP2 (red), and glutamate receptors are labeled with Gria2/3 (green). This technique was used to analyze the role of Foxo3 in the adult mouse cochlea. For more information see Gilels et al. (18409–18424).
