Background: Smartphone addiction, which represents a behavioral concern, has been found to correlate with a diverse range of mental health problems among the undergraduate students. Meanwhile, the modes of behavioral inhibition/activation showed specific characteristics in smartphone addiction individuals. Therefore, clarifying the interaction of mental health and behavioral modes with smartphone addiction is urgent. Here, we used a cross-sectional design, aiming to explore the network interactions among smartphone addiction, mental health (depression, anxiety, stress, loneliness and life satisfaction), and the behavioral inhibition/activation system (BIS/BAS) in undergraduate students. Methods: We employed network analysis and community detection in R, to investigate the centrality and edge connections, which are the mainly index of key factors and interaction effects between factors respectively. The study was carried out among 701 participants with an average age of 18.27 ± 1.57 years old, all of whom had completed self-report scales. Results: The network analysis results suggested that depression and anxiety, the behavioral activation of fun seeking, reward responsiveness and behavioral inhibition had significantly higher centrality than the other mental health and BIS/BAS factors respectively. When combining the connections of network analysis and community detection, the stronger connections mainly present in the inner domain of mental health factors and the BIS/BAS, respectively. The findings regarding the transdomain connections imply that stress is likely to serve as a mediator in the relationships between smartphone addiction and both depression as well as BAS-Drive. Conclusion: Therefore, the current study suggests that although common psychological and behavioral system problems may play a dominant role in smartphone addiction among undergraduate students, it is still necessary to consider whether other factors such as stress may play a potential moderating role. The new insight will help to enhance mental health and facilitating proper smartphone use management to avoid the aggravation of addiction problems among undergraduate student.

Neuropathic pain (NP) is a prevalent clinical condition resulting from diseases or injuries affecting the somatosensory system. Conventional analgesics often exhibit limited efficacy, leading to suboptimal therapeutic outcomes. The pathogenesis of NP is complex and involves multiple mechanisms. The existing evidence suggests that maladaptive neuronal plasticity plays a central role in NP development. Additionally, emerging research highlights the contribution of neuroinflammatory responses mediated by glial cells in the onset of NP and associated sensory hypersensitivity. Among non-invasive neuromodulation techniques, transcranial direct current stimulation (tDCS) has gained prominence as a potential treatment for NP. Numerous studies have demonstrated its analgesic effects; however, the precise regulatory mechanisms remain unclear. The current evidence indicates that tDCS may alleviate NP by enhancing glial–neuronal interactions, which suppress nociceptive signaling pathways and reduce pain sensitivity. The reciprocal modulation between tDCS-mediated anti-inflammatory actions, as evidenced by decreased levels of pro-inflammatory cytokines and increased levels of anti-inflammatory mediators, and its facilitation of adaptive neural plasticity represents a particularly compelling therapeutic axis. This review elucidates inflammatory regulation by tDCS as a fundamental mechanism for NP alleviation, while delineating important unresolved questions regarding these complex interactions.

Background: Psychological qualities issues among adolescents are increasingly prominent, and effective interventions are urgently needed. Campus Football Activities has shown potential in improving Psychological qualities, but the underlying mechanisms remain unclear.Objectives: This study aimed to explore the impact of campus football activities on adolescents' psychological qualities, along with the underlying mechanisms and pathways involved, and further examines the effects of an 8-week campus football program on adolescents' psychological qualities.Methods: First, an 8-week campus football intervention was conducted on 68 Chinese adolescents aged 16–18 years [mean age 16.865 years (standard deviation 0.636)] to explore the impact of campus football on adolescents' psychological qualities. Then, a cross-sectional survey was carried out on 431 adolescents from Chinese high school. The mean age of study participants varied from 16 to 18 years [mean 16.865 (0.816)]. The Sport Behavior Scale, Sport Cognitive Level Psychological Assessment Scale, Trait Sport Confidence Scale, and Adolescent Willpower Quality Scale were used to construct a structural equation model. This model revealed the effects of campus football on promoting adolescents' sports behavior, sports cognitive levels, confidence in sports, and willpower qualities, as well as their internal relationships.Results: Significant differences in campus football behaviors, sports cognitive levels, sports self-confidence, and willpower qualities existed among adolescents following campus football activities. Furthermore, the direct effect of campus football behaviors on willpower qualities was significant. The mediating and chain mediating effects of sports cognitive levels, sports self-confidence, and the combination of sports cognitive levels and sports self-confidence between campus football behaviors and willpower qualities were also significant.Conclusion: Campus football activities can enhance adolescents' psychological qualities across: sports behaviors, sports cognitive levels, sports self-confidence, and willpower qualities. The internal action pathway is that campus football behaviors directly influence willpower qualities, and also improve willpower qualities through the respective mediating effects and joint chain mediating effect of sports cognitive levels and sports self-confidence.

This study aimed to explore the implicit procedural learning and associated neural oscillatory activities in adults with Developmental Coordination Disorder (DCD) using electroencephalography (EEG). The sample consisted of 22 adults with DCD (14 females) and 22 age-matched controls (11 females), aged 18-21 years. Participants engaged in a modified Serial Reaction Time Task (SRTT) designed to assess implicit sequence learning. Behavioral results did not show significant differences in reaction times or speed-accuracy trade-off indices between the DCD and control groups, suggesting that implicit sequence learning might not be impaired in adults with DCD. However, EEG analysis revealed marked differences in theta oscillation energies; notably, the DCD group displayed higher theta amplitudes in the frontal region and delayed peaks in frontal-region theta bands compared to controls. These findings suggest that while behavioral performance might appear typical, the underlying neural processes in the DCD group are significantly different and underscore procedural learning deficits in adults with DCD. The results enrich our understanding of the neural underpinnings of DCD and offer insights for devising targeted interventions to improve procedural learning abilities in affected individuals.
