Abstract

The interspike interval (ISI) of 17 out of 156 fibers had integer multiples temporal rhythm patterm, in which all the ISI were integer multiples of a basic ISI and a return map of their ISI could be constructed as a crystal grid structure. This temporal pattern could be modified by Na~(+) channel and K~(+) channel on their membranes.
