(A) Left: Insula seed in green. Right: Resulting t-map showing regions in which abstainers had significantly higher strength of RSS than relapsers within the insular network. t-Map is overlaid on a MNI brain in radiological orientation (right is left). (B) Bar graphs (with ±1 standard error bars) showing strength of RSS between insula and regions with significant differences between abstainers (blue bars) and relapsers (green bars). ANCOVA analysis showed that differences did not reach significance after controlling for noise (see F and Sig. values in Table 7B). RSS, resting-state synchrony; PHG, parahippocampal gyrus.
