Configuration of Biosemi for brainmaps_referencing online

[goldfoxy]

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 amplitude. I believe this is due to the active CRM/DRL site close to Cz when using the Biosemi system. Hence I need to get specific information as how to configure the Biosemi system for proper recording.

I really hope someone can help me!

Choose the linked ears as your reference off-line, see http://www.biosemi.com/faq/cms&drl.htm
