These results support the findings of the current study, in which the manipulation of extracellular potassium concentrations changed the membrane potential and that this membrane potential may be affected by the permeability of other ions besides …show more content…
Dulhunty (1977) also found that the extracellular potassium and chloride concentrations could affect the membrane potential in such a way that could be modelled by the GHK equation, depending on the concentration of chloride intracellularly. These results also support the hypothesis and results that the GHK equation, which accounts for the permeability and concentration of several ions across the membrane, may provide a good model for predicting the membrane potential
