Nerve membrane current noise: direct measurements under voltage clamp.

Abstract

Fluctuations in the steady-state current of the membrane of the lobster giant axon have been measured under voltage-clamp conditions. These fluctuations have a power density spectrum that is inversely proportional to frequency. The magnitude of the fluctuations is determined largely by the potassium component of the membrane current.
