Effect of ionic channel blockade on Vm responses to shocks of strength 20 V/cm in the 800-μm long fiber. (A) Shock-induced polarization transients at seven recording sites along the fiber identified by triangles for aLRd (control) and for aLRd with 75% reduction of ICa(L) (denoted as ICa(L) 25%) models. Shock pulse is shown at the bottom. (B) Spatial distribution of ΔVm (%APA) along the strand 3 ms after shock onset in the control aLRd case and in the case of ICa(L) 25%. (C) Asymmetry ratios 3 ms after shock onset in the cases of control, ICa(L) 25%, original LRd ICa(L) reduction by 75% (denoted as ICa(L),O 25%), and IK1 reduction by 75% (denoted as IK1 25%).
