Cover legend: Subunits of voltage-gated potassium channels are distributed differentially within functional microdomains of the auditory nerve. Kv1.2 subunits (green) localize to the somatic membrane and juxtaparanodes of spiral ganglion neurons, whereas Kv3.1b subunits (red) are apparent at nodes of Ranvier. For more information, see Smith et al. (pages 11221–11232).
