(a) With the approaching cluster the duration of the bursts increase (n=6/6 intercluster periods/animals, one-way ANOVA, F(1,53)=, P=0.012), as well as, the line length parameter (b) (n=6/6 intercluster periods/animals, one-way ANOVA, F(1,53)=, P=0.016). (c) The proximity to critical transition is also marked by the increasing rate of epileptic bursts (n=6/6 intercluster periods/animals, one-way ANOVA, F(1,59)=, P=0.005). (d) Increase in spatial correlation reflects enhanced propagation of bursts to the hippocampus and motor cortex increased (n=6/6 intercluster periods/animals, one-way ANOVA, F(1,53)=, P=0.001). (e) The autocorrelation (n=6/6 intercluster periods/animals, one-way ANOVA, F(1,53)=, P=0.928), signal variance (f) (n=6/6 intercluster periods/animals, one-way ANOVA, F(1,53)=, P =0.814) and the first spectral moment (g) (n=6/6 intercluster periods/animals, one-way ANOVA, F(1,53)=, P =0.128) did not show significant changes with approaching cluster. The significance of changes in temporal profiles was analyzed using one-way ANOVA. Circles and error bars represent mean and s.e.m. respectively.
