The optimal order of the AR model of the time series at five ROI’s.

V: visual cortex; PCC: parietal cortex; PreM: pre-motor cortex; S: sensorimotor cortex; M: motor cortex. L: left hemisphere (R condition). R: right hemisphere (L condition).

V：视觉皮层（visual cortex）；PCC：顶叶皮层（parietal cortex）；PreM：运动前皮层（pre-motor cortex）；S：感觉运动皮层（sensorimotor cortex）；M：运动皮层（motor cortex）。L指代左半球（对应右侧条件），R指代右半球（对应左侧条件）。
