Figure 4. Correlations between alpha power and HEP difference between high- (HA) and low-arousal (LA) mood inductions.

Figure 4

(a) Correlation between alpha power during HA and the HEP difference between HA and LA at the electrodes of cluster 2 (see Fig. 3); (b) The same correlation as in a, but for alpha power during LA mood induction; (c) Correlation between the alpha power difference between HA and LA and the HEP difference between these two conditions.
