The proportional correlations between maximal dV/dt vs. spike propagation fidelity or velocity indicate an involvement of VGSCs in spike propagation. A) illustrates maximal dV/dt vs. spiking time at cerebellar Purkinje cells when somatic spikes are induced at 200 Hz. B) shows a proportional relationship between normalized spike propagation velocity and maximal dV/dt, where the data of spike propagation velocity are from red symbols in Figure 2E. C) shows proportional relationship between spike propagation fidelity and maximal dV/dt, in which the data of spike propagation fidelity are from red symbols in Figure 2F.
