The photoreceptor’s membrane potential in the dark is determined by nongated (leakage) K+ channels, which tend to drive the membrane potential to the potassium equilibrium potential of –70mV, and by open cGMP-gated channels which admit a dark current of about 50 pA (mainly Na+). This current keeps ...
