Heat map for the p values of the center procedure divided by the P values for the right center one at each electrode location for a) $\frac{{\alpha }_c}{{\alpha }_{RC}}$, b) $\frac{{\beta }_c}{{\beta }_{RC}}$, c) $\frac{{\gamma }_c}{{\gamma }_{RC}}$, d) $\frac{{(\alpha /\beta )}_C}{{(\alpha /\beta )}_{RC}}$, e) $\frac{{(\alpha /\gamma )}_C}{{(\alpha /\gamma )}_{RC}}$ f) $\frac{{(\beta /\gamma )}_C}{{(\beta /\gamma )}_{RC}}$. All ratios were logarithmically scaled before plotting.
