TIME-FREQUENCY DYNAMICS OF RESTING BRAIN CONNECTIVITY MEASURED WITH FMRI

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 大多数使用fMRI研究静息态（“内在”）功能连接的方法都假设时间 平稳性，例如跨扫描持续时间计算的相关性和数据驱动的分解。然而，在这方面， 基于任务的功能磁共振成像研究和动物电生理学的证据都表明， 可以在几秒到几分钟的时间尺度内表现出动态变化。 要了解卢卡斯中心正在进行的其他项目，请访问http://rsl.stanford.edu/ （卢卡斯年度报告和 ISMRM 2011摘要）

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Most studies of resting-state ("intrinsic") functional connectivity using fMRI employ methods that assume temporal stationarity, such as correlation and data-driven decompositions computed across the duration of the scan. However, evidence from both task-based fMRI studies and animal electrophysiology suggests that intrinsic functional connectivity may exhibit dynamic changes within time scales of seconds to minutes.
