We examined neurophysiological markers associated with emotion regulation in children comorbid for externalizing and internalizing problems before and after treatment. We hypothesized that treatment success would correspond with reduced ventral prefrontal activation, and increased dorsomedial prefrontal activation, at the time point of an event-related potential (ERP) associated with inhibitory control. Twenty-seven 8- to 12-year-old children (with usable data) were tested before and after a 14-week community-based treatment program and assessed as to improvement status. Fifteen 8- to 12-year-olds from the normal population (with usable data) were tested over the same interval. All children completed an emotion-induction go/no-go task while fitted with a 128-channel electrode net at each test session. ERP amplitudes, and estimates of cortical activation in prefrontal regions of interest, were measured at the peak of the “inhibitory” N2 and compared between improvers, nonimprovers, and nonclinical children. ERP amplitudes showed no group differences. However, improvers showed an overall reduction in ventral prefrontal activation from pretreatment to posttreatment, bringing them in line with nonclinical children, whereas ventral activation remained high for nonimprovers. Both improvers and nonimprovers showed high dorsal activation relative to nonclinical children. Supplementary analyses indicated that only ventral prefrontal regions, and only within the N2 time window, showed decreased activity from pre- to posttreatment, suggesting changes in regulatory processes rather than in overall emotional arousal. These cortically mediated changes may permit a reduction in the overengaged, rigid style of emotion regulation characteristic of children with behavior problems.

Frontolimbic activity in a frustrating task: Covariation between patterns of coping and individual differences in externalizing and internalizing symptoms / Ida MOADAB in Development and Psychopathology, 22-2 (May 2010)  

Public ISBD [article]  inDevelopment and Psychopathology > 22-2 (May 2010) . - p.391-404 Titre : Frontolimbic activity in a frustrating task: Covariation between patterns of coping and individual differences in externalizing and internalizing symptoms Type de document : Texte imprimé et/ou numérique Auteurs : Ida MOADAB, Auteur ; Thomas J. DISHION, Auteur ; Tara GILBERT, Auteur ; Don M. TUCKER, Auteur Année de publication : 2010 Article en page(s) : p.391-404 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Many problem behaviors in youth have been attributed to maladaptive self-regulation in response to frustration. Frontolimbic networks that promote flexible as well as over- and undercontrolled regulation could provide evidence linking cortical mechanisms of self-regulation to the development of internalizing or externalizing symptomology. Specifically, ineffective dorsally mediated inhibitory control may be associated with rule-breaking and substance use behaviors, whereas overengagement of ventral limbic systems responsible for self-monitoring of errors may increase risk of developing anxious and depressed symptomology. In this study, a sample of 9- to 13-year-old children were presented with an emotional go/no-go task. Event-related potentials were used to identify differences in cortical mechanisms related to inhibitory control (indexed with the stimulus-locked medial frontal negativity) and self-monitoring (indexed with the error-related negativity). These measurements were then related to externalizing and internalizing behaviors. As predicted, externalizing problems were associated with smaller medial frontal negativity amplitudes, which indicate undercontrolled self-regulation and poor dorsal mediation of actions. Internalizing symptoms were related to larger error-related negativity amplitudes, demonstrating overregulation and overengagement of ventral limbic systems. These findings suggest that the use of event-related potential methodology with paradigms that elicit cognition–emotion can provide insight into the neural mechanisms of regulatory deficits that result in problem behaviors in youth.
