Brain region for each MEG channel

Hi, Dear Researchers, I need the brain region corresponding to each MEG channels, how can I get this information?
Best wishes,

There's no one-to-one correspondence between a sensor and a brain region. Sensors pick up activity from multiple brain regions. You can visualize such sensitivity brain map by mapping the so-called lead fields of each sensor on the cortex. Please consult (see View Lead Field Vector)

Ok, I see. Thanks !
