[Eeglablist] Electrode placement for the mu rhythm

I have only one channel and would like to record the mu rhythm on the left 
hemisphere. What is the best placement for the two active electrodes and the 
reference electrode? Everyone else has multiple channels and records 
laplacian and CAR references.
Thanks
Deirdre
