Figure 6. The inactivation time constant in non-electrolyte solutions as a function of solution osmolarity.

Data obtained in glycerol (○), erythritol (•), glucose (□) and sucrose (▪) solutions are plotted. A, percentage change in t_h at +20 mV plotted as a function of Π. The data are plotted with s.d. values (vertical bars). Data were fitted with eqn (17), and then α_h and δ_h for the four different non-electrolytes were obtained. B, α_h plotted as a function of membrane potential. C, δ_h plotted as a function of membrane potential. D, δ_h obtained by fitting the data with eqn (17) with α_h fixed equal to the averaged value of α_g (Table 2), as in Fig. 5D, plotted as a function of membrane potential.
