Treatment. The reference electrodes A1, A2 are excluded from the above plot. For
every heatmap each axis corresponds to the electrodes and the intensity of each pixel
is associated with the amount of the mutual information (in nats) with reference
to the colorbar. Correspondence between numbers (in axes) and electrodes can be
found in the first column of Table 19.2.
months of adjunctive AED treatment. In Table 19.2, we present all the electrode
pairs that were decoupled (mutual information after treatment was statistically sig-
nificant lower than before treatment).
Also in order to visualize the topological distribution of the decoupled chan-
nels we divided (F-Frontal, C-central, T-temporal, P-pariental, O-occipital) and we
counted the number of pairs that were decoupled between each of these regions.
Results are presented in Table 19.3.
