本视频介绍了在审查通过有针对性的任务/进程从事认知控制网络功能连接年龄相关的变化的方法。该技术是基于fMRI数据的多变量分析。
该程序的总体目标是识别与任务切换相关的大脑网络,并测试这些网络的功能连接性中与年龄相关的差异。这是通过首先从儿童和成人收集 FMRI 数据,同时完成维度变化卡片排序任务来实现的。对数据进行预处理后,功能卷被分解为一组统计上独立的源或组件。
与执行功能和任务绩效相关的组成部分分别通过模板匹配和线性建模来选择。最后一步是确定所选组件中的功能连接对于成人和儿童来说是否不同。最终,基于 ICA 的 FMRI 分析可用于识别与任务切换相关的网络,并测试这些网络功能组织中与年龄相关的差异。
