Different Resting-State Functional Connectivity Alterations in Smokers and Nonsmokers with Internet Gaming Addiction

Figure 3

Significant between-group differences in rsFC of different brain regions with PCC between nonsmokers with IGA and HC subjects. Compared with the HC group, nonsmokers with IGA exhibited increased rsFC in left cerebellum posterior lobe, left medial prefrontal cortex, right caudate, and right insula. Decreased rsFC was found in left calcarine cortex, right superior parietal lobule, right middle occipital gyrus, left middle frontal gyrus, left precuneus, and left inferior temporal gyrus (, AlphaSim-corrected). The -score bars are shown on the right. Red indicates nonsmokers with IGA > HC and blue indicates nonsmokers with IGA < HC. Note: the left part of the figure (L) represents the participant’s left side; (R) represents the participant’s right side. IGA: Internet gaming addiction; rsFC: resting-state functional connectivity; HC: healthy control, PCC: posterior cingulate cortex.
