FCtools: Functional Connectivity Tools

Junhong Yu, Charly Hugo Alexandre Billaud

Analyzing and visualizing brain connectivity data, including network-based statistics (NBS) for linear and linear mixed models, both at edge level and functional network level (Yeo's 7-networks (Schaefer et al. (2017) )). Plots in- clude edge-wise connectograms, chord diagrams, network connec- tograms, heatmaps, …

Effect of wearables with behavioral prompts on physical and cognitive outcomes in community-dwelling older adults: preliminary results of a pilot randomized controlled trial

Kar Yin Lee, Savannah Siew, Tat Lee Teo, Kuang Chua Chua et autres

Introduction The global rise in life expectancy has driven research into aging-related vulnerabilities, particularly cognitive frailty. Physical activity interventions have been identified as a protective factor, and technology, such as wearable devices, may enhance engagement. This pilot RCT explores mobile phone applications …

Predicting Mental Rotation and Arithmetic Abilities in Adolescents Using Resting‐State Functional Connectivity

Shih Yang Ngieng, Junhong Yu, Darren J. Yeo

ABSTRACT Mental rotation (MR), a core spatial ability, is linked to arithmetic performance, with meta‐analytic findings suggesting shared parietal and frontal neural correlates. While intrinsic functional connectivity has been shown to predict math ability in children, its predictive value for MR remains …

Psychosocial factors associated with engagement and efficacy of mindfulness intervention in the classroom

Savannah Kiah Hui Siew, Junhong Yu

BACKGROUND: Mindfulness practice has been associated with a range of benefits in the literature. However, intervention effects show substantial person-to-person variability, and the individual differences underlying this variability remain underexamined. Identifying the psychosocial predictors of the practice can increase our understanding of …

Resting‐State and Task Functional Magnetic Resonance Imaging Network Topology Metrics With no Threshold Selection to Predict Cognition

Charly Hugo Alexandre Billaud, Junhong Yu

Network topology measures characterise brain networks' organisation. Graph theoretical approaches have shown fMRI topology metrics' association with cognitive performance. Because arbitrary connectivity threshold selection biases such metrics, alternatives including the minimum spanning tree (MST) and novel measures following principles of persistent homology …

Fixel‐based analysis and free‐water metrics in subjective cognitive decline and cognitive impairment no dementia

Zheng Long Lee, Mervin Tee, Wei Ying Tan, Xiangyuan Huang et autres

INTRODUCTION: People with subjective cognitive decline (SCD) and cognitive impairment, no dementia (CIND) have higher risks of dementia. This study investigated whether fixel-based and free-water (FW) metrics, which examine the white matter (WM) structure, differ in SCD and CIND and their relationships …

Social mind at rest: resting-state connectivity associated with social thought relates to friendship quality

Yi-Sheng Wong, Junhong Yu

Although mind wandering is often associated with adverse outcomes, certain thought content may support adaptive functions. This study investigated how latent dimensions of resting-state thought relate to adaptive functioning, mental, emotional, and behavioral problems, and resting-state connectivity patterns in 130 healthy adults. …

Dysregulation of Rho‐Associated Coiled‐Coil Protein Kinase1 Depletes Neural Stem Cell Pool and Impairs Hippocampal Neurogenesis After Traumatic Brain Injury

Chaoqun Yao, Jun Zhong, Qianying Huang, Zhongwei Bao et autres

Traumatic brain injury (TBI) represents a global health burden, often resulting in persistent neurological deficits due to impaired hippocampal neurogenesis. Nevertheless, the temporal progression of post-TBI neurogenesis and its molecular mechanisms remain elusive. To investigate the mechanism of impaired hippocampal neurogenesis and …

Retraction Note: Mindfulness-based randomized controlled trials led to brain structural changes: an anatomical likelihood meta-analysis

Savannah Kiah Hui Siew, Junhong Yu

After publication of this study concerns were raised about the way the exclusion/inclusion criteria were applied. Specifically, four null-finding papers accounting for data from 40% of participants were excluded from the analyses, while other studies were included despite being done in very …
