Sustained Attention Task (gradCPT) Dataset using simultaneous EEG-fMRI and DTI

This dataset includes simultaneous recordings of electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and diffusion-weighted imaging (DWI) from 28 participants aged 19 to 42 years. The fMRI and DWI data were acquired using a 3T MRI scanner (Siemens Magnetom Prisma), and the EEG was recorded using 64 channels (Brain Product BrainCap MR with Multirodes).

The following tasks were performed: resting state (eyes open and closed), checkerboard (15Hz), gradCPT, and imagery task. Raw files can be found in the subfolders, while preprocessed files are available in the derivatives folder. For more detailed information about the file structure, please refer to the readme files.

本数据集收录了28名年龄介于19至42岁的受试者的同步记录数据，涵盖脑电图（electroencephalography, EEG）、功能磁共振成像（functional magnetic resonance imaging, fMRI）及弥散加权成像（diffusion-weighted imaging, DWI）三种模态。其中功能磁共振成像与弥散加权成像数据采用3T磁共振扫描仪（西门子Magnetom Prisma）采集，脑电图数据则通过64通道设备（Brain Product BrainCap MR搭配Multirodes电极帽）完成记录。
本数据集涵盖以下实验范式：静息态（睁眼与闭眼两种状态）、15Hz棋盘格刺激任务、gradCPT任务以及想象任务。原始文件存储于各子文件夹中，预处理文件可在derivatives文件夹内获取。如需了解文件结构的详细信息，请参阅readme文件。
