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).\n\nThe following tasks were performed: resting state (eyes open and closed), checkerboard (15Hz), gradCPT, and imagery task.
