Abstract The default mode network is essential for higher-order cognitive processes and is composed of an extensive network of functional and structural connections. Early in fetal life, the default mode network shows strong connectivity with other functional networks; however, the association with structural development is not well understood. In this study, resting-state functional magnetic...

Background: Previous studies have demonstrated that tinnitus is associated with neural changes in the cerebral cortex. This study is aimed at investigating the central nervous characteristics of tinnitus patients with different severity by using a rs-EEG. Participants and methods: rs-EEG was recorded in fifty-seven patients with chronic tinnitus and twenty-seven healthy controls. Tinnitus...

연구 목적: 이 연구는 노화과정에서 기본모드연결망의 비효율적인 기능으로 인한 인지저하를 예방하고 인지기능을 향상시키기 위한 명상의 역할을 고찰하고자 한다.연구 방법: 연구방법은 노화와 정신질환과의 관계, 과제관련 연결망과 기본모드 연결망의 기능 및 역할 상호 관련성 그리고 명상의 역할에 대한 문헌조사를 하였다.연구 내용: 이 논문의 연구내용은 기본모드연결망이 고차적인 인지기능을 수행하지만 과제와 관련된 작업을 수행할 때는 기본모드연결망을 억제할 수 있어야 한다. 하지만 노화과정에서 이러한 억제가 감소되면서 노인의 정신건강상태가 위협을 받게 된다. 명상 수행은 노인들의 인지기능 저하를 막아줄 수 있다.결론 및 제언: 명상은 노인들의 인지저하를 늦출 수 있고, 건강한 라이프 스타일을 장려함으로써 노인들의...

ABSTRACT Transcranial photobiomodulation (tPBM) has been used for cognitive enhancement in healthy people. However, its effect on creativity has not been investigated. The default mode network (DMN) is associated with divergent thinking (DT; but not convergent thinking, CT), and also with anxiety, which in turn has been negatively related to creativity. We aimed to use tPBM over the DMN to...

Sleep plays an important role in healthy neurocognitive development, and poor sleep is linked to cognitive and emotional dysfunction. Studies in adults suggest that shorter sleep duration and poor sleep quality may disrupt core neurocognitive networks, particularly the default mode network (DMN)-a network implicated in internal cognitive processing and rumination. Here, we examine the...

Objectives: Youth raised in stressful environments are at increased risk for developing impulsive traits, which are a robust precursor of problem behaviors. Sleep may mediate the link between stress and problem behaviors as it is both sensitive to stress and essential for neurocognitive development underlying behavioral control during adolescence. The default mode network (DMN) is a brain...

Adolescents experience alarmingly high rates of major depressive disorder (MDD), however, gold-standard treatments are only effective for ~50% of youth. Accordingly, there is a critical need to develop novel interventions, particularly ones that target neural mechanisms believed to potentiate depressive symptoms. Directly addressing this gap, we developed mindfulness-based fMRI neurofeedback...

Background: Alterations in the default mode network (DMN) connectivity across pain stages suggest a possible DMN involvement in the transition to persistent pain. Aim: This study examined whether pain-free DMN connectivity at lower alpha oscillations (8-10 Hz) accounts for a unique variation in experimental peak pain intensity beyond the contribution of factors known to influence pain...

External tasks evoke characteristic fMRI BOLD signal deactivations in the default mode network (DMN). However, for the corresponding metabolic glucose demands both decreases and increases have been reported. To resolve this discrepancy, functional PET/MRI data from 50 healthy subjects performing Tetris were combined with previously published data sets of working memory, visual and motor...

Recent research has shown that the Default Mode Network (DMN) typically exhibits increased activation during processing of social and personal information but shows deactivation during working memory (WM) tasks. Previously, we reported the Frontal Parietal Network (FPN) and DMN showed coactivation during task preparation whereas the DMN exhibited deactivation during task execution in working...
