Cover legend: Pseudocolored overlay of peak Ca²⁺ responses (Fluo4 fluorescence) in enteric neurons and enteric glia within a myenteric ganglion from the guinea pig distal colon. Ca²⁺ responses were stimulated in enteric neurons with the nicotinic agonist epibatidine and in enteric glia with the purine ATP. For more information, see the article by Gulbransen et al. in this issue (pages 6801–6809).
