About the cover: Crystal structure of the GluR2 subunit and identification of agonist-binding residues. The left side is a backbone representation of the subunit, with kainate docked into its binding site. The image on the right provides a close-up view of the ligand-binding pocket. These images are a portion of Figure 2 from Dingledine et al., page 7 in this issue. See the article for the complete figure in color.
