Dataset-1 was from a published dataset [22 (link)] which included 34 healthy participants (aged 19–31 years, 18 females). That study was approved by the Ethics Committee of the Center for Cognition and Brain Disorders, Hangzhou Normal University. Informed consent was obtained from each participant.
For each participant, four resting state sessions were scanned with two conditions EO and EC by BOLD and arterial spinlabeling (ASL), respectively. The order of the four sessions was counterbalanced across participants. The ASL data were not used in the current study. Dataset-1 was acquired using a GE MR-750 3.0 T scanner (GE Medical Systems, Waukesha, WI) at the Center for Cognition and Brain Disorders of Hangzhou Normal University. Each scan consisted of 240 contiguous EPI functional volumes (TR = 2000 ms; TE = 30 ms; flip angle = 60°; 37 axial slices; field of view (FOV) = 220 × 220 mm2, matrix = 64 × 64; in-plane resolution 3.44 × 3.44 × 3.4 mm3. For spatial normalization, a spoiled gradient-recalled pulse sequence was also used (176 sagittal slices; slice thickness = 1 mm; TR = 8100 ms; TE = 3.1 ms; flip angle = 9°; FOV = 250 × 250 mm2).
