The data is the raw DICOM data of fMRI. The experiment included eight runs for each subject. There were four task blocks and five resting blocks in each run. In each 12-s task block, the participants were required to view 12 pictures from one of the four types (house, face, car and cat) and press the left button if any two sequential images were the same. During the 12-s control block, the subjects were required to view the fixation “+” on the screen.

本数据集为功能磁共振成像（fMRI）的原始DICOM数据。每名受试者参与8次扫描时段。每次扫描时段包含4个任务块与5个静息块。在每个时长12秒的任务块中，受试者需观看4类（房屋、人脸、汽车与猫）图片中的一类共12张，若任意两张连续图片完全一致，则按下左侧按键。在时长12秒的静息块中，受试者需注视屏幕上的固定十字"+"。
