Fig. 5. Percentage of cells with capacitance steps. This graph shows the percentage of cells that showed exocytotic steps. The steps are categorised into three groups: solitary steps, solitary flicker steps and burst steps. STB was present in all stimulation experiments as indicated. Cells measured: 104 in SBM; 48 at physiological temperature (phys. temp.); 41 in carbachol (Carb); 23 in carbachol plus staurosporine (Carb. +SSP).
