AA task and behavioral results. A, Schematic representation of the affect-congruent and affect-incongruent conditions in the AA task. B, Average reaction times for each participant (n = 40) and condition. Responses are slower during incongruent trials. *t(39) = −4.33, p < 0.001.

Emotional control increases theta-band power in aPFC. A, Time–frequency plot of between conditions power differences (congruency effect: incongruent − congruent/congruent + incongruent) averaged over sensors with a significant effect (see B). Time 0: response onset. The dashed box shows the time–frequency interval with a significant congruency effect (−350 to −100 ms before response; 6 Hz). B, Topographic distribution of sensors with a significant congruency effect at 6 Hz (stars). C, Changes over time in theta-band power (6 Hz) averaged across significant sensors (see B). The epoch with a significant difference between conditions is marked in gray. D, Cortical distribution of theta-band congruency effects. E, Time series of 6 Hz activity extracted from right frontal pole/superior frontal gyrus (20 40 50). F, Cortical distribution of correlations between theta-band and behavioral congruency effects, with a significant cluster over aPFC (dashed black circle, MNI coordinates of local maximum: 40 48 −6). G, Correlation between theta-band and behavioral congruency effects. Black dots represent measurements from each participant. Theta-band power changes are extracted from the local maximum in aPFC.

Emotional control decreases beta-band power in parietal and frontal cortex. A, Time–frequency plot of between conditions power differences (congruency effect: incongruent − congruent/congruent + incongruent) averaged over sensors with a significant effect (see B). Time 0: response onset. The dashed box shows the time–frequency interval with a significant congruency effect (−600 to 0 ms before response; 14–26 Hz). B, Topographic distribution of sensors with a significant congruency effect at 14–26 Hz (stars). C, changes over time in beta-band power (14–26 Hz) averaged across significant sensors (see B). The epoch with a significant difference between conditions is marked in gray. D, Cortical distribution of beta-band congruency effects (center frequency, 18 Hz). E, Time series of 18 Hz activity extracted from superior parietal lobule (44 −40 56). F, Cortical distribution of correlations between beta-band (18 Hz) and behavioral congruency effects, with a significant cluster over right precentral gyrus (MNI coordinates of local maximum: 48 −2 36). G, Correlation between beta-band and behavioral congruency effects. Black dots represent measurements from each participant. Beta-band power changes are extracted from the right precentral maximum.

Emotional control increases connectivity between aPFC and frontoparietal areas. A, Cortical distribution (uncorrected for multiple comparisons) of correlations between beta-band congruency effects and theta-band congruency effects extracted from aPFC (in red, from Fig. 2E). The cluster over the right precentral gyrus (MNI coordinates of local maximum: 50 −10 36) is significant. B, Correlation between aPFC theta-band and precentral beta-band congruency effects. Black dots represent measurements from each participant. Beta-band power changes are extracted from the right precentral maximum.

Emotional control increases gamma-band power in parietal and frontal cortex during peaks of theta-band oscillations in aPFC. A, Time–frequency plot of between conditions power differences (congruency effect: incongruent − congruent/congruent + incongruent) averaged over sensors with a significant effect (see B). Time 0: response onset. The dashed box shows the time–frequency interval with a significant congruency effect (−350 to −50 ms before response; 60–90 Hz). B, Topographic distribution of sensors with a significant congruency effect at 60–90 Hz (stars). C, Changes over time in gamma-band power (60–90 Hz) averaged across significant sensors (see B). D, Cortical distribution of relative gamma-band congruency effects, with a significant cluster around the left central sulcus (−28 −32 64). E, Time series of 60–90 Hz activity extracted from left central sulcus (−28 −32 64). F, Time–frequency plot of gamma-band power congruency effects extracted from the local maximum in the left central sulcus (F) phase-locked to the aPFC theta-band signal before response. Contours are drawn around significant clusters where power is stronger in incongruent versus congruent trials. G, Event-related field of the theta-band signal extracted from aPFC.
