Configuration of Biosemi for brainmaps_referencing online

Hi there, I desperately need to know how to re-reference the Biosemi montage to do online recording using the linked-mastoids as reference, or linked-ears. Currently all brainmaps recorded on Biosemi (which I do on Neuroguide) show a sink at central sites, i.e., decreased whole frequency bands ampli...

Can anyone advise as to whether I need additional references for fEMG using the extra ‘EX’ electrodes, or will CMS/DRL suffice for this measurement also? (N...

I know this is likely to sound very dumb but can anyone advise as to whether I need additional references using the extra ‘EX’ electrodes, or will CMS/DRL suffice for subsequent hemisphe...
