I'm interested in brain-computer interfaces (BCIs). I'm working with the OpenEEG system (from Olimex) as well as a custom system that I've built.
Currently, I'm aiming to build a BCI based on looking for Mu-waves from the sensorimotor cortex. This is a fairly standard technique...for those who might not be familiar, I've written some background here:
My question is: have any of you been successful in recording Mu waves? Where did you put your reference electrode and where did you put your "bias" (or "ground") electrode?
I would appreciate any suggestions that you might have!
