Fig. 3: Correlation results between effective connections and IAT scores through parametric empirical Bayesian framework.

a shows each parameter’s effect size after Bayesian model averaging for the mean of all subjects, and c shows the corresponding posterior probabilities. b shows the effect size of correlations between each parameter and IAT scores and d shows the corresponding posterior probabilities. Here the threshold of the posterior probability is set to 0.9, so the current results indicate that a positive correlation between connection strength and IAT is observed in effective connection from the MFG to left putamen (i.e., parameter 3 in b, d). IGD: 174 subjects; RGU: 244 subjects. Note: parameter 1: self-connection from left MFG to left MFG; parameter 2: effective connection from left MFG to left NAcc; parameter 3: effective connection from left MFG to left putamen; parameter 4: effective connection from left MFG to right MFG; parameter 5: effective connection from left NAcc to left MFG; parameter 6: self-connection from left NAcc to left NAcc; parameter 7: effective connection from left NAcc to left putamen; parameter 8: effective connection from left NAcc to right MFG; parameter 9: effective connection from left putamen to left MFG; parameter 10: effective connection from left putamen to left NAcc; parameter 11: self-connection from left putamen to left putamen; parameter 12: effective connection from left putamen to right MFG; parameter 13: effective connection from right MFG to left MFG; parameter 14: effective connection from right MFG to left NAcc; parameter 15: effective connection from right MFG to left putamen; parameter 16: self-connection from right MFG to right MFG; IGD: 22 subjects; RGU: 18 subjects.
