Cover picture: Immunogold labeling (5 nm) for AMPA receptors (GluR1-4) on an intramembrane particle (IMP) cluster in postnatal 3-d-old rat Purkinje cells as revealed by SDS-digested freeze-fracture replica labeling. The IMP cluster on the exoplasmic fracture-face represents excitatory synaptic area. For details, see the article by Tanaka et al. in this issue. (pages 799–807).
