“…Furthermore, alpha- or delta-band activity was closely related to the degree of internet use disorder in both functional and resting states ( Balconi, Campanella, & Finocchiaro, 2017 ; Burleigh, Griffiths, Sumich, Wang, & Kuss, 2020 ; Wang & Griskova-Bulanova, 2018 ; H. Wang, Sun et al., 2020 ). Several fMRI studies also found that smartphone use disorder was associated with functional abnormalities in attention- or reward-related brain areas ( Han & Kim, 2022 ; Henemann et al., 2022 ; Pyeon et al., 2021 ). Thus, it is reasonable to speculate that topological deviations in top-down control and reward-motivated networks were associated with smartphone use disorder.…”

BackgroundIncreasing research has examined the factors related to smartphone use disorder. However, limited research has explored its neural basis.AimsWe aimed to examine the relationship between the topology of the resting-state electroencephalography (rs-EEG) brain network and smartphone use disorder using minimum spanning tree analysis. Furthermore, we examined how negative emotions mediate this relationship.MethodsThis study included 113 young, healthy adults (mean age = 20.87 years, 46.9% males).ResultsThe results showed that the alpha- and delta-band kappas and delta-band leaf fraction were positively correlated with smartphone use disorder. In contrast, the alpha-band diameter was negatively correlated with smartphone use disorder. Negative emotions fully mediated the relationship between alpha-band kappa and alpha-band diameter and smartphone use disorder. Furthermore, negative emotions partially mediated the relationship between delta-band kappa and smartphone use disorder. The findings suggest that excessive scale-free alpha- and delta-band brain networks contribute to the emergence of smartphone use disorder. In addition, the findings also demonstrate that negative emotions and smartphone use disorder share the same neural basis. Negative emotions play a mediating role in the association between topological deviations and smartphone use disorder.DiscussionTo the best of our knowledge, this is the first study to examine the neural basis of smartphone use disorder from the perspective of the topology of the rs-EEG brain network. Therefore, neuromodulation may be a potential intervention for smartphone use disorder.
