The brain mappings of the logistic regression between the diagnostic decision, d (dependent variable; wrong = 0, right = 1), and H ( e _i ), which were calculated for each of the electrodes (independent variables). The normalized ${\beta }_i\overline{H}\left(e_i\right)$ values obtained for each electrode were color-coded such that yellow to dark-blue areas were associated with increasingly values of positive β _i and pink to dark-red areas were associated with increasingly values of negative β _i . The areas in white were not statically significant and the difference between the mappings in A (see Table 3) and B (see Table 4) is the use of expertise as a control variable in B.
