Fluctuations in membrane potential of axons and the problem of coding
1.Fluctuations in the resting membrane potential of frog nerve fibers were analysed in the frequency range from 1 to 10 000 radians per second. The power spectrum follows a 1/f law.2.Latency fluctuations have been measured for different stimulus intensities. The relation between standard deviation and mean follows a quadratic law. It can be shown for a number of different receptors that this relation is in part linear in part quadratic.
