Theta band PLI and network characteristics for patients and healthy controls.

<p>Parameters were averaged for each sensor on a group level and displayed on a helmet-shaped surface to show global patterns of differences between patient groups. Note that particularly in LGG patients, theta band clustering and participation coefficients show global alterations irrespective of local PLI values. Abbreviations: CTL = healthy controls; LGG = low-grade glioma patients; HGG = high-grade glioma patients; NGL = non-glioma patients; PLI = phase lag index; C_w,i* = nodal clustering coefficient; L_w,i* = nodal path length; = within-module degree z-score; = participation coefficient. <i>*In the analysis we use normalized average weighted clustering coefficient (C_w/C_ws) and normalized average weighted shortest path length (L_w/L_ws) instead of the unnormalized values for each vertex i, C_w,i and L_w,i which are visualized here. C_w/C_ws and L_w/L_ws are calculated by first averaging over nodes and then dividing C_w and L_w by a reference value C_ws and L_ws, in order to get normalized values. However, this normalization does not affect the spatial distribution of C_w,i and L_w,i, and therefore the original data is presented.</i>
