Full details are in the STAR Methods. Here, P_{Na, leak} = 1.96e⁻⁷, P_{Cl, leak} = 1.5e⁻⁷, and P_{K, leak} = 0.6e⁻⁷(μm/ms). The equilibrium potentials for Na⁺, K⁺ and Cl⁻ were 56.64 mV, −87.06 mV, and −95.07 mV at 295.15 K, respectively, and were calculated using the Nernst equation for each ion with concentrations identical to those used in the experiments.
