Cover legend: 3D reconstructions of a cerebellar granule cell (top left), a unipolar brush cell (bottom left), and a Golgi cell (largest cell). The cells were filled with biocytin during whole-cell recording in three adult cerebellar acute slice preparations, and a streptavadin-Alexa Fluor 555 conjugation was used to visualize the cells with confocal imaging. For more information, see the article by Houston et al. in this issue (pages 3887–3897).
