基于任务的功能神经影像数据的大规模共享有可能为大脑心理功能的组织提供新的见解，但神经影像领域在数据共享资源的开发方面落后于生物科学的其他领域。本文介绍了 OpenFMRI 项目（可在线访问 http://www.openfmri.org），该项目旨在为神经影像学界提供资源，以支持基于任务的 fMRI 研究的开放共享。我们描述了该项目背后的动机，特别关注该项目如何解决基于任务的 fMRI 数据共享的一些众所周知的挑战。提出了对当前数据库的初步分析结果，表明能够在任务对比之间进行分类，并具有较高的泛化准确度，以及从其激活图中识别单个受试者的能力，具有较高的准确度。聚类分析表明，统计图之间的相似关系与相关任务所涉及的心理功能具有某种程度的有序关系。这些结果凸显了该项目支持对心理过程与大脑功能之间关系进行大规模多变量分析的潜力。
The large-scale sharing of task-based functional neuroimaging data has the potential to allow novel insights into the organization of mental function in the brain, but the field of neuroimaging has lagged behind other areas of bioscience in the development of data sharing resources. This paper describes the OpenFMRI project (accessible online at http://www.openfmri.org), which aims to provide the neuroimaging community with a resource to support open sharing of task-based fMRI studies. We describe the motivation behind the project, focusing particularly on how this project addresses some of the well-known challenges to sharing of task-based fMRI data. Results from a preliminary analysis of the current database are presented, which demonstrate the ability to classify between task contrasts with high generalization accuracy across subjects, and the ability to identify individual subjects from their activation maps with moderately high accuracy. Clustering analyses show that the similarity relations between statistical maps have a somewhat orderly relation to the mental functions engaged by the relevant tasks. These results highlight the potential of the project to support large-scale multivariate analyses of the relation between mental processes and brain function.
