Fig. 3: FPN hyper- connectivity is significantly decreased in the SS group after ECT treatment.

Identified negative FCs from FPN were decreased in the SS_post group compared to the SS_pre group (paired t-test, p = 0.001), brain regions of these connections were shown on the right. SS_Pre patients with suicide symptoms at pre-treatment, SS_Post patients with suicide symptoms at post-treatment, FPN frontoparietal network, MOT sensorimotor network, VAN ventral attention network, DMN default mode network.
