Figure 4: Further examples of Recurrence Plots.

From: Following a potential epileptogenic insult, prolonged high rates of nonlinear dynamical regimes of intermittency type is the hallmark of epileptogenesis

Figure 4

The upper RP is associated to an ECoG epoch of a mouse treated with albumin + SJN2511, selected after approximately 32 hours from the beginning of the treatment. The lower RP is associated to an ECoG epoch of a mouse treated with vehicle + Dextran, selected after approximately 16 hours from the beginning of the treatment. Very different patterns of recurrent points can emerge in a RP, thus giving rise to different amounts of laminarity (vertical lines) and determinism (diagonal lines, see also the Supplementary Discussion), which usually change from epoch to epoch. Nevertheless, we stress again that the RPs are not correlated with the actual amount of laminarity and determinism of the time-series. This is due to our analytical approach, as explained in the ‘Methods’ section, paragraph ‘Normalization of the variable LAM’. See also the legend of Fig. 1. Therefore, we discourage the reader to compare the RPs to each other in order to have a visual representation of how the amount of occurrence of laminarity states varies among the experimental groups.
