Power-Law Inter-Spike Interval Distributions Infer a Conditional Maximization of Entropy in Cortical Neurons
(A)–(C) Optimal values of beta-2 fitting parameters α, R and κ for pyramidal (triangles) and fast-spiking (circles) neurons recorded at various depths of the cortex. As in Figure 2, the color code indicates the motor components represented by the individual neurons. The values were determined by nonlinear least square method (Materials and Methods). (D) The relationship between α and κ values over the recorded neural population. (E) The relationship between α and η values. The latter was determined by linear regression of the power-law tails of ISI distributions (see Figure 2C).
