In-Depth Information
Table 19.2: In this table we present all the electrode pairs that were decoupled for
each one of the four patients (columns 2-4). One electrode pair is decoupled when
mutual information after treatment is statistically lower (based on paired
t
-test) than
mutual information before treatment. For example, electrodes of the first line and
fourth column indicate the decoupled electrodes between electrode Fp1 (first line)
for the third patient (fourth column)

Table 19.3: Number of channels per patient per site that were decoupled after treat-
ment. F, T, C, P, O correspond to the frontal, temporal, central, pariental, and occip-
ital channels correspondingly. It is easy to see that for patient 1 we have the most
decoupled channels

, therefore, Fp1 is the driver,
and vice versa. The above results suggest the existing treatment effects on the cou-
pling strength and the directionality between different cortex regions.
