Figure 1. Illustration of the method to extract the non-Gaussianity in the ISI fluctuations.

Figure 1

(A) ISI's of a spike train of a neuron are displayed chronologically. (B) Cumulated ISI's. (C)(D) ISI fluctuations were calculated by detrending (defined in the text) at Inline graphic (C) and Inline graphic (D). The spike train was taken from a cortical neuron #12 when the animal was awake.
