Figure 1

Differences in point set and whole head registration techniques. The first row shows the original locations for the participant (fiducials, 10-10 electrodes, GSN electrodes) and average MRI template (fiducials, 10-10). The second through fourth rows show the registration between the comparable locations for the participant and template, which generate an affine matrix, multiplied by the GSN 128 locations, to produce the transformed electrodes in the space of the average MRI template. (Fiducial marks: Nz = Nasion, Vz = Vertex, Iz=Inion, LPA=Left Preauricular point, RPA = Right Preauricular point, LMa = Left Mastoid, and RMz = Right Mastoid.
