Broadening the Impact of Developmental Neuroscience on the Study of Adolescence
Having been a significance source of the renewed interested in the adolescent period, developmental neuroscience now needs to build upon its achievements to date and expand in several areas in order to broaden its impact upon the field. Addressing both typical and atypical development, examining the interaction between brain development and the social environment, studying change over time, and including attention to population diversity can help to produce a truly integrative science of adolescent development. The papers in the special section provide nice examples of how developmental neuroscience can make such expansion...

Longitudinal Associations Between Family Aggression, Externalizing Behavior, and the Structure and Function of the Amygdala
Using longitudinal data from 21 adolescents, we assessed family aggression (via mother, father, and youth report) in early adolescence, externalizing behavior in mid‐adolescence, and magnetic resonance imaging (MRI) data in late adolescence. Amygdalae were manually traced, and used as seed regions for resting state analyses. Both family aggression and subsequent externalizing behavior predicted larger right amygdala volumes and stronger amygdala‐frontolimbic/salience network connectivity and weaker amygdala‐posterior cingulate connectivity. Externalizing behavior in mid‐adolescence mediated associations between fam...

Dyadic Neural Similarity During Stress in Mother –Child Dyads
We examined dyadic neural representational similarity as adolescents completed a stress task and mothers observed their child's performance during the same task. On average, mothers and their children did not show similar neural patterns during stress. However, neural similarity varied depending on family connectedness, such that only dyads reporting high family connectedness showed similar neural profiles. Importantly, increased neural similarity was associated with reduced stress in youth, suggesting that shared neural profiles in mother–child dyads enhance adolescents’ psychological well‐being.

Do Hostile School Environments Promote Social Deviance by Shaping Neural Responses to Social Exclusion?
The present study examined adolescents’ neural responses to social exclusion as a mediator of past exposure to a hostile school environment (HSE) and later social deviance, and whether family connectedness buffered these associations. Participants (166 Mexican‐origin adolescents, 54.4% female) reported on their HSE exposure and family connectedness across Grades 9–11. Six months later, neural responses to social exclusion were measured. Finally, social deviance was self‐reported in Grades 9 and 12. The HSE–social deviance link was mediated by greater reactivity to social deviance in subgenual anterior cingulate c...

Prefrontal Cortical Response to Negative Social Words Links Social Risk to Depressive Symptoms in Adolescence
We examined the extent to which neural response to negatively valenced social information might help to account for the relationship between social risk and depressive symptoms in youth. Forty‐nine youth were scanned while identifying the emotional valence of words that connoted social status. They also completed questionnaires assessing self‐reported social risk factors and depressive symptoms. Mediation analysis revealed that reduced dorsolateral prefrontal cortex activity in response to negative social status words explained the positive association between social risk and depressive symptoms. These findings suggest...

Neural Substrates of Counterfactual Emotions After Risky Decisions in Late Adolescents and Young Adults
Adolescents’ neural substrates of emotional reactions to the consequences of risky decisions are poorly understood. In this functional magnetic resonance imaging study, 30 late adolescents and 30 young adults made risky and neutral decisions in social scenarios and received valenced outcomes. Negative outcomes in risky decisions eliciting regret, as compared with negative outcomes in neutral decisions eliciting disappointment, activated executive control (orbitofrontal cortex) and self‐relevance regions (middle temporal gyrus [MTG], posterior cingulate cortex, and precuneus) for both age groups. Young adults showed mor...

Neural Correlates of Risky Sex and Response Inhibition in High ‐Risk Adolescents
We examined the correlation between condom use and fMRI‐based Stroop response in a large ethnically diverse sample of high‐risk adolescents (n = 171). Partially replicating previous literature, sexual risk was positively correlated with blood‐oxygen‐level‐dependent (BOLD) activation in the middle frontal gyrus during response inhibition, highlighting the relevance of this region during risky sexual decision making within this age group.

Positive and Negative Affect and Adolescent Adjustment: Moderation Effects of Prefrontal Functioning
We examined whether cognitive control moderates the effects of emotion on adolescent internalizing and externalizing symptomatology in a longitudinal study of 138 adolescents. Self‐reported positive affect (PA) and negative affect and behavioral and neural indicators of cognitive control, indexed by performance and prefrontal hemodynamic response during a cognitive interference task, were collected at Time 1. Self‐reported internalizing and externalizing symptomatology were collected at Time 1 and Time 2 (1 year later). Results indicated that higher PA predicted decreases in externalizing symptomatology, but only for ...

Pathways to Youth Behavior: The Role of Genetic, Neural, and Behavioral Markers
Neural and temperamental mechanisms through which a genetic risk marker in the γ‐amino butyric acid α2 receptor subunit (GABRA2) impacts adolescent functioning were investigated. Participants (N = 80; 29 female) completed an emotional word task during functional magnetic resonance imaging. Behavioral control, negative emotionality, and resiliency temperament constructs were assessed. Externalizing and internalizing problems were the outcomes. Those with the GABRA2 minor allele had reduced activation to positive words in the angular gyrus, middle temporal gyrus, and cerebellum, and to negative words in frontal, pariet...

Connecting Theory and Methods in Adolescent Brain Research
Networks are often implicated in theories of adolescent brain development, but they are not regularly examined in empirical studies. The aim of this article is to address this disconnect between theory and quantitative methodology, using the dual systems model of adolescent decision making as a prototype. After reviewing the key task‐related connectivity methods that have been applied in the adolescent neuroimaging literature (seed‐based correlations, psychophysiological interactions, and dynamic causal modeling), a novel connectivity method is introduced (extended unified structural equation modeling). The potential ...
