Figure Lengend Snippet: Illustration of electrode arrangements; ( a ) displays the EEG electrodes positions and numbers, and ( b ) shows a representation matrix (A) of 12 × 12 for the EEG 128-channel sensor net over the whole scalp, with some electrode positions repeated to fill the matrix array. This matrix presents the areas of the brain according to the corresponding color, as shown in the legend to the right of the matrix. The left and right hemispheres divide the matrix into 2 equal and symmetrical parts of 2 sub matrices of 12 × 6 each. Positions A 1,3 and A 1,10 , starting from the bottom left, are empty.
Article Snippet: The EEG technology used for this study was a HydroCel Geodesic Sensor Net (HCGSN), 128 electrodes dense-array electroencephalography (EEG) produced by Electrical Geodesics, Inc., USA [ ].
