[FieldTrip] Beamforming oscillatory responses in MEG and EEG data tutorial

[Kaelasha Tyler]

Hi all,

Just a question:
I was running through the 'Beamforming oscillatory responses in MEG and EEG data' tutorial, and at one plot, the strongest motor response is located in the center of the head.  The tutorial asks "Can you explain this finding?"
Has anyone else done this tutorial?
Because I am not at all sure why a motor response would show up in the centre of the head.
Can anyone enlighten me?

When I have been getting results that look like this, I kept feeling there was an error or some artefact going on.
