    Study Notes

    Development of the Emotional Brain

    • Adolescence is a time of significant neural reorganization, impacting emotion reactivity and regulation.

    • Emotional development involves a cascade of changes in limbic and cognitive control circuitry, particularly pronounced during adolescence due to the need for self-regulation in varied social and emotional situations.

    • Circuit changes progress hierarchically, from subcortico-subcortical to subcortico-cortical to cortico-subcortical, and finally to cortico-cortical, with each level crucial for the next.

    • Adolescent behaviors may be explained by two competing brain systems: cognitive control and emotive systems.

    • The imbalance model highlights circuit-based changes in emotion reactivity and regulation with age, emphasizing interaction between subcortical and cortical circuits across development. Changes in fine-tuning of connections and circuits influence emotional behavior.

    Neural Circuitry and Emotion

    • Subcortical regions, including the amygdala and ventral striatum, play a role in emotional reactivity.
      • The ventral striatum learns positive outcomes, interacting with the amygdala.
      • The amygdala learns the emotional significance of environmental cues triggering motivated actions.
    • Medial prefrontal cortex is linked to fear and emotional regulation.
    • Cortico-cortical connections (e.g., lateral prefrontal cortex and medial prefrontal regions) mediate the interface between cognitive and emotional processes.
    • Development involves hierarchical refinement of circuits from subcortical to cortical levels, leading to changes in emotional reactivity and regulation.

    Adolescent Emotional Reactivity and Regulation

    • The amygdala and ventral striatum have been studied in isolation, but recent research suggests complex interactions and roles beyond simple valence associations.
    • Impulsivity to emotional cues, regardless of valence, is associated with specific developmental changes in the amygdala-ventral striatum circuit.
    • Increased medial prefrontal-amygdala connectivity correlates with better emotional cue-driven cognitive control in adolescents.
    • Cortico-subcortical connectivity (e.g., amygdala-prefrontal connections) is implicated in emotion regulation.
    • Cortical modulation of subcortical outputs through top-down processes may diminish emotive and reflexive responses in adolescents.

    Emotional Development in Adults

    • Emotional regulation matures over time, reaching adult levels in response to both brief and prolonged emotional states.
    • Cognitive control remains susceptible to negative emotional influences into young adulthood, as lateral and ventromedial prefrontal circuitries continue to develop.
    • Neuroimaging studies offer evidence of emotional influences on cognitive control into young adulthood.
    • Developmentally-sensitive legal interpretations must account for ongoing neurodevelopmental changes in adolescents.
