Table 2. Duration of calcium transients in gliding control, 8-Br-cADPR and dantrolene-treated parasites.

Results are means±S.E.M. (s); n=9 (three parasites were analysed in each of the three separate experiments). Duration is the average time between the start of successive cycles; Peak-to-low is the time from the highest to the lowest intensity during a cycle; Time between is the average time between successive intensity peaks; Average amplitude is the average change in pixel intensity for the first flux, as shown in Figure 6. *P<0.05, significantly different from control (two-tailed Student's t test).
