Imaging acquisition
Imaging was performed on a 3.0 Telsa scanner (GE SIGNA) with a standard whole-head coil at the First Affiliated Hospital, Zhejiang University School of Medicine. The participants were asked to lie on the scanner with their eyes closed. Foam cushions were positioned on either side of the head to restrict head motion, and earplugs were used to reduce the noise. High-resolution 3D anatomical images were captured through T1-weighted magnetization prepared rapid acquisition gradient-echo (MPRAGE) sequence. The parameters used were: TR = 7.1 ms; TE = 2.9 ms; FOV = 260 × 260 mm
