218-功能连接性映射方法的基准测试

09 Nov 2025

Description

这篇文章提供了一项关于功能连接性 (FC) 映射方法的全面基准测试,因为它在神经科学中越来越受欢迎。作者使用多达 239 种成对统计量来评估不同 FC 矩阵在捕获枢纽、结构-功能耦合、个体指纹识别和脑-行为预测等规范特征方面的差异。研究发现,所选统计量对功能网络结构有显著影响,并指出 协方差和精度等测量方法在许多期望的属性上表现良好。该报告强调,研究人员应根据其特定的神经生理学机制和研究问题,定制成对统计量的选择,以优化 FC 映射。References: Liu Z Q, Luppi A I, Hansen J Y, et al.
