Figure 6.
Voltage-dependent effects of dantrolene on the peak (left column) and on the steady level (right column) of SR calcium permeability. The steady level was measured as the average of the values during the last 20 ms of the test pulse. The voltage dependence of either component was fitted with in every fiber. The obtained maximum (, Rrel,i[max]) in control on the given fiber was used to normalize the values before averaging and plotting them. The parameters obtained by fitting the voltage dependence with and averaged over the fibers are presented in Table . The same fibers and symbols as in Fig. 4 are used.
