Inspection of the factor loadings for total power (Figure 1a) revealed that the first factor peaked at ~40 Hz and 50 ms, corresponding to the GBR, and accounted for 12.59% of the variance. Inspection of the factor loadings for evoked power (Figure 1b) revealed that the first factor peaked at ~40 Hz and 50 ms, corresponding to the GBR, and accounted for 7.62% of the variance. Inspection of the factor loadings for PLF (Figure 1c) revealed that the third factor peaked at ~40 Hz and 50 ms, corresponding to the GBR, and accounted for 14.96% of the variance.
