Relationship between the Neurofeedback Training Effect on the Left Amygdala Activation and Individual Psychological Scores.

<p><b>A) Correlation with the Difficulty Identifying Feelings (TAS-20).</b> The training effect for the left amygdala was correlated with the participants' insight into their feelings. Thus the more highly the participants rated their capacity for identifying their own feelings (based on the Difficulty Identifying Feelings sub-scale of the Toronto Alexithymia Scale, TAS-20), the more they increased the BOLD signal in the left amygdala during training. <b>B) Correlation with the Susceptibility to Anger (EC).</b> The higher the participants rated their sensitivity to other peoples' anger (based on the Susceptibility to Anger sub-scale of the Emotional Contagion scale, EC), the less BOLD activation was observed in their left amygdala during training. The activation levels shown (in both A and B) are averages across the three neurofeedback training runs (Runs 1–3) for each subject in the Experimental group.
