Table 2.
The significantly different clusters for the contrasts between the two intervention groups (experimental NFB vs sham-control NFB) and the two timepoints (Post-intervention vs Pre-intervention). The reverse contrasts (if significant) are shown with negative T-statistic values. Abbreviations: dlPFC - Dorsolateral Prefrontal Cortex, vlPFC - Ventrolateral Prefrontal Cortex.
