Fig. 5.

Expanded theta band connectivity tile from Fig. 1 at the same statistical threshold (Z = 4.45, q < 0.00005), illustrating theta band connections significantly associated with the suicidal thoughts (ST) factor. Also shown is a glass brain perspective of the connections (middle right), as well as maps of the nodes with size scaled by the total Z value summed over all connections (far right). While anterior insula (AI) and left hippocampus still showed a large number of connections associated with the ST factor, there was greater involvement of frontal connections, particularly the left and right dorsolateral prefrontal cortex (DLPFC) and orbitofrontal regions of interest (ROIs). Greyscale colorbar is the same as in Fig. 3, omitted here for space.
