Fluctuations of Resting Neural Membrane Potential

The membrane potential of myelinated axons in the resting state shows fluctuations for which the power per cycle of bandwidth is inversely proportional to frequency between 1 and 10,000 radians per second. Reduction of potassium ion flux leads to a decrease in noise power.
