Abstract
The fluctuations of the voltage across the resting membrane of
myelinated nerve fibers have been analyzed. They show a 1/f spectrum
and a Gaussian amplitude distribution and are related to the net
flow of potassium through the membrane. When the average membrane
voltage is made more negative by means of an external current,
depolarizing deflections can be observed. They cause an asymmetry
in the noise amplitude distribution and a marked increase in the
subaudio spectral components of the noise. The depolarizing deflections
can be attributed to batch-wise inflow of sodium ions. Possible
mechanism of both types of membrane voltage fluctuations are
discussed.
