Figure 4. Quantification of the impact of medium's conductivity.

(A) Electric field at 50% of survival rate as a function of the external medium conductivity. (B) Steepness of survival decay as a function of conductivity. (C) Steepness of survival decay as a function of the electric field strength at 50% of survival rate. Electric field at 50% of survival rate and steepness of survival decay were extracted from the fit of the data in Fig. 3. Each value of the extracellular medium has been assigned a different symbol: 1.5 S/m (square), 0.6 S/m (diamond), 0.375 S/m (triangles) and 0.1 S/m (circles).
