Fig. 3. The effects of InsP₃, caffeine and carbachol (CCh) on STOCs. Depolarisation from -69 mV to -10 mV (iv) elevated [Ca²⁺]_i (iii) and activated STOCs (ii). InsP₃ ( ${uparrow}$ ), caffeine (Caff, 10 mM, v) and CCh (50 µM) each increased [Ca²⁺]_i (iii) and reversibly inhibited STOCs (ii and expanded time scale i).
