神经影像学利用还原论的刺激,推进了我们对人类心理学的理解,这些刺激通常与大脑自然遇到的信息不相似。它提高了我们对大脑网络组织的理解,主要是通过分析“休息状态”数据,这些数据无法验证网络的功能。我们制作了一个“自然神经影像数据库”(NNDb v1.0),以允许在更生态的条件下更完整地了解大脑,在此期间可以标记网络。86名参与者接受了行为测试,并观看了10部全长电影之一,同时获得了功能性磁共振成像。所得到的时间序列数据被证明是高质量的,具有良好的信噪比,很少的离群值和低运动。数据驱动的功能分析提供了数据质量的进一步证据。他们还演示了准确的时间序列/电影对齐以及如何使用电影注释来标记网络。NNDb可以用来回答以前用标准的神经成像方法无法解决的问题,推进我们对大脑在真实的世界中如何工作的知识。描述报告数据的机器可访问元数据文件:10.6084/m9.figshare.12869855
Neuroimaging has advanced our understanding of human psychology using reductionist stimuli that often do not resemble information the brain naturally encounters. It has improved our understanding of the network organization of the brain mostly through analyses of ‘resting-state’ data for which the functions of networks cannot be verifiably labelled. We make a ‘Naturalistic Neuroimaging Database’ (NNDb v1.0) publically available to allow for a more complete understanding of the brain under more ecological conditions during which networks can be labelled. Eighty-six participants underwent behavioural testing and watched one of 10 full-length movies while functional magnetic resonance imaging was acquired. Resulting timeseries data are shown to be of high quality, with good signal-to-noise ratio, few outliers and low movement. Data-driven functional analyses provide further evidence of data quality. They also demonstrate accurate timeseries/movie alignment and how movie annotations might be used to label networks. The NNDb can be used to answer questions previously unaddressed with standard neuroimaging approaches, progressing our knowledge of how the brain works in the real world.
