Illustration of the three different montage electrodes referencing methods. (a) Linked Mastoids Montage; left sites are referenced to the A1 while right site are referenced to A2, and the central sites are referenced to the half of the sum of A1 and A2. (b) C.A.R.; each site is referenced to the average of all electrode sites. (c) Large Laplacian; each site is referenced to the weighted average of their one-step neighbors.
