The pictures below show the standard "10-20" system names for the EEG caps that are currently used in the MEG lab. This would be helpful in order to have a reference of where a channel number (1-74)  is in terms of the 10-20 system. Since the MEG lab has two types of caps, the old blue ones and the newer white ones, there are two images below showing the channel names for both:

(Look here for a [[http://imaging.mrc-cbu.cam.ac.uk/meg/VectorviewDescription|description of our Vectorview system]], including sensor and electrode layouts).

'''Note that the difference between the naming/numbering of the two caps is that the old caps have channels FP1 and FP2 as numbers #1 and #3 respectively, whereas on the new caps channels FP1 and FP2 have been removed and instead PO9 is  #1 and PO10 is #3. '''

Attached is also an Excel sheet with the channel names, numbers and pins (for the old caps; for the new, replace FP1/FP2 with PO9/PO10 respectively)
