In rat CA1 pyramidal neurons under sub- and supra-threshold conditions, our previous study showed the potentials of Cantor coding, which is theoretically proposed by Tsuda and Kuroda. However, the coding could be explained by mean rate coding simply depended on input pattern history of the peak amplitude of each input. In order to confirm that Cantor coding includes any other factors except mean rate coding, we applied three spatially different patterns of electrical stimulations with similar peak amplitudes. Although the responses did not show the statistical significant self-similar property, the membrane responses show significant clustering property. Our results suggest that some factors, which does not simply depend on mean firing rate coding, was included in Cantor coding processing.
