Examples of phase-phase plots computed for single Time Shift (top) and Random Permutation (bottom) surrogate runs of 100 (left) and 1200 s (right) for the same hippocampal LFP as in Figure 10A. Notice that, for the longer LFP epoch, the randomly permutated surrogate exhibits less discernible stripes than the time-shifted one.
