Effect of Brain-to-Skull Conductivity Ratio on EEG Source Localization Accuracy

Table 1

Mean and STD values of the localization errors (mm) for shallow, middle, and deep dipole source for different BSCRs with 31-electrode montage when the noise-contaminated EEG measurements are simulated by 1000 times randomly generated GWN.

Inverse	Forward of shallow source		Forward of middle source		Forward of deep source
	20	80	20	80	20	80
20	9.6 ± 4.6	16.8 ± 5.7	9.0 ± 4.4	13.2 ± 5.1	9.6 ± 4.3	12.1 ± 5.0
80	12.2 ± 5.7	10.7 ± 5.5	17.3 ± 7.0	11.9 ± 5.7	16.6 ± 6.7	13.3 ± 5.7
