Figure 6. Results of a realistic EEG simulation – a patch was assumed around left frontal lobe: (a) Exact patch location; (b) Source distribution of (Case 1); (c) Source distribution of (Case 2); (d) Source distribution of (Case 3). All quantities were normalized with respect to their own maximum value. Sources that exceed 0.1 are visualized. SNR = 7 dB. DF values of (b), (c), and (d) are 0.065, 0.069, and 0.153, respectively.
