Self-esteem gates the coupling between cultural estrangement and the default mode network

Scientific Reports August 15, 2026 Morio Aki, Naoya Oishi, Sayaka Yoshimura et al.

Increasing multiculturalism and globalization have increased the discrepancies between socially-shared norms and personal values. This study examined whether the association between Cultural Estrangement (CE) and resting-state functional connectivity (FC) of the default mode network (DMN) is moderated by self-esteem (SE). In total, 170 healthy Japanese adults (20–70 years) were recruited, 70 of...

Default mode network hub disruption links problematic use of the Internet to brain network disorganization.

Comprehensive Psychiatry July 1, 2026 Nagara Takao, Naoya Oishi, Qi Dai et al.

Problematic Use of the Internet (PUI) has been associated with functional alterations in the default mode network (DMN), which contains critical hubs in the entire brain network. Previous studies have predicted that hub disruption leads to widespread network alterations; however, whether DMN functional connectivity mediates the relationship between PUI and global network topology remains...

Alterations of the default mode network, salience network, and frontoparietal network in non-problematic Internet use and their association with mood regulation: from an internet literacy perspective

Frontiers in Neuroscience July 1, 2025 Mami Shibata, Kosuke Tsurumi, Kei Kobayashi et al.

IntroductionAlthough a number of neuroimaging studies on problematic internet use (PIU) have been conducted, few studies on non-problematic internet use (non-PIU) are available; therefore, the influences of non-PIU on brain function are unclear. Resting-state functional connectivity (rsFC) could be an appropriate tool to investigate subclinical samples, such as non-PIU, to capture the...
