Design outcomes

Primary

MeasureTime frame
Primary outcomes were (i) the safety and tolerability of MEG examination, (ii) the maximum power in the left ventral Brodmann area 9/46 in the dorsolateral prefrontal cortex (DLPFC) and the power-ratio of the inferior parietal lobule (IPL)/ medial ventral occipital cortex (MVOcC) in the dorsal stream during the optic flow task.

Secondary

MeasureTime frame
Secondary outcomes were [i] brain activity at the dorsal stream and DLPFC during the optic flow task, and [ii] brain activity of mean frequency and alpha peak frequency at resting with eye closed mean frequency and alpha peak frequency
