Mapping upper limb movements to the somatosensory/motor cortex at 7T: associated data outputs

This dataset provides supporting data for our pilot study on practical scan-length considerations for mapping upper limb movements to the somatosensory/motor cortex at 7T, conducted at the Athinoula A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Harvard Medical School, in collaboration with Massachusetts Institute of Technology. Here is what is contained in each subfolder: "figures - runs_compare" This folder has figures comparing activations for different number of runs across all upper limb movements. In the associated publication, these figures appear in the supplement. "figures - tasks_compare" This folder has figures comparing activations across different upper limb movements. In the associated publication, these figures appear in the supplement. "FSL FEAT screenshots" This folder shows screenshots of fMRI data pre-processing and analysis in FSL FEAT. "FSL outputs" This folder has several subfolders, each corresponding to an independent analysis with different number of runs (2 through 8) with both left and right arm movements. Each of these subfolders contains FSL output of thresholded Z-statistic NIfTI images as well as corresponding figures.' The home folder also contains a reference mean functional image and the M1/S1 anatomical mask from the Harvard-Oxford atlas.本数据集为我们开展的一项预实验提供配套支撑数据，该预实验聚焦于7T场强下将上肢运动映射至体感/运动皮层（somatosensory/motor cortex）时的实际扫描时长考量相关研究。本研究由哈佛医学院（Harvard Medical School）麻省总医院（Massachusetts General Hospital）阿蒂努拉·A·马蒂诺斯生物影像中心（Athinoula A. Martinos Center for Biomedical Imaging）牵头开展，并与麻省理工学院（Massachusetts Institute of Technology）合作完成。 各子文件夹内容说明如下： "figures - runs_compare"：该文件夹收录了针对所有上肢运动任务、不同扫描次数下的脑激活对比图谱。在相关发表论文中，此类图表刊载于补充材料章节。 "figures - tasks_compare"：该文件夹收录了不同上肢运动任务间的脑激活对比图谱。在相关发表论文中，此类图表刊载于补充材料章节。 "FSL FEAT screenshots"：该文件夹展示了使用FSL FEAT进行功能性磁共振成像（fMRI）数据预处理与分析的操作截图。 "FSL outputs"：该文件夹包含多个子文件夹，每个子文件夹对应一项独立分析，分别对应2至8次扫描次数以及左右侧上肢运动任务的组合。每个子文件夹均包含经阈值化处理的Z统计量NIfTI格式图像，以及对应的配套可视化图表。 数据集根目录还包含一份参考平均功能图像，以及来自哈佛-牛津脑图谱（Harvard-Oxford atlas）的初级运动皮层（Primary Motor Cortex, M1）与初级体感皮层（Primary Somatosensory Cortex, S1）解剖掩码。
