Fig. 3.

Relation between the number of spikes (left), ripples (middle) and FRs (right) and the eigenvector centrality (EC) in the FR (upper) and gamma (lower) frequency band.

Colored lines are the patient specific regression lines. The bold black line represents the fixed effect of the model. The fixed coefficient β represents the average relation between the dependent variable and the %Events (spikes, ripples or FRs). We show a negative association between the number of all types of epileptic events and node centrality in the gamma band and the trend towards the opposite, a positive association, between the number of epileptic events and node centrality in the fast ripple frequency band.
