Resting-state functional connectivity (rsFC) between the VTA and left/right NAcc. The label’ Left NAcc and VTA’ refers to the rsFC strength between these two regions of interest. Bars with oblique lines show the mean values of rsFC between the VTA and left/right NAcc in IGD, bars with dots show the mean value of rsFC between the VTA and left/right NAcc in HC, error bars the standard errors of the mean
