Cover picture: Suppression of Ca²⁺ syntillas in chromaffin cells increases frequency and quantal size of exocytotic events. (Top) Ca²⁺ imaging of syntillas demonstrates presence in control cell (left) and absence with ryanodine treatment (right), displayed as pseudo-colored change in fluorescence from baseline. (Middle) Amperometric current recorded from the cell depicted above. (Bottom) Summarized effects of ryanodine (see article by Lefkowitz et al., 267–280).
