Exocytosis of many trichocysts is accompanied by large currents. (A) During the frame shown, only 6 of 25 released trichocysts were visible (white dots). When settled, they could be documented much more clearly (not shown) than during rapid expulsion. The current recording (inset) shows the foot of the rising phase of the current signal, which is shown in its full duration in (B; extracellularly recorded outward current after application of a submaximal dose of AED). The current corresponds to a charge of 40 pC.
