    Unstable functional brain states and reduced cerebro-cerebellar modularity in elderly individuals with subjective cognitive decline by Wuhai Tao, Xiaojie Lu, Shuaike Yuan, Peixuan Ye, Zhanjun Zhang, Qing Guan, Hehui Li

    Published 2025-01-01
    “…In the current study, we employed dynamic functional connectivity and large-scale brain network approaches to investigate the pathological characteristics of dynamic brain states and cerebro-cerebellar collaboration between SCD (n = 32) and the healthy elderly (n = 29) using resting-state fMRI. Two-way repeated measures ANOVA and permutation t-tests revealed significant group differences, with individuals with SCD exhibiting shorter state duration and more frequent transitions between states compared to the healthy elderly individuals. …”
