在这里,我们提出了一个测试-重新测试的数据集的功能磁共振成像(FMRI)数据在静态采集。22名参与者在相隔一周的两次会议中接受了扫描。每次扫描包括两次1.5 mm的全脑各向同性扫描和一次0.75 mm的前额叶皮质各向同性扫描,总共提供六个时间点。此外,数据集还包括情绪、持续注意力、血压、呼吸、脉搏和自我产生的思想内容(走神)的测量。这些数据使得能够在高空间分辨率下调查会话内和会话间变异性的来源,不仅限于生理变化,而且还包括认知和情感状态的变化。数据集附有详细的实验方案和所有使用的刺激的源代码。
Here we present a test-retest dataset of functional magnetic resonance imaging (fMRI) data acquired at rest. 22 participants were scanned during two sessions spaced one week apart. Each session includes two 1.5 mm isotropic whole-brain scans and one 0.75 mm isotropic scan of the prefrontal cortex, giving a total of six time-points. Additionally, the dataset includes measures of mood, sustained attention, blood pressure, respiration, pulse, and the content of self-generated thoughts (mind wandering). This data enables the investigation of sources of both intra- and inter-session variability not only limited to physiological changes, but also including alterations in cognitive and affective states, at high spatial resolution. The dataset is accompanied by a detailed experimental protocol and source code of all stimuli used.
