“…Fourth, we did not test the association of brain measures with cognitive outcomes although we did conduct a sensitivity analysis excluding those with mild cognitive impairment ( Dong et al, 2015 ; Fletcher et al, 2018 ). Fifth, we did not test for modification by social determinants of health (e.g., access to insurance, literacy; Rodriguez et al, 2022 ; Sadhu et al, 2019 ) which may point to potential modifiable factors related to brain aging. Further work will more completely address these issues.…”

“…Moreover, the protective effects of greater collective efficacy were relatively more robust than the effects of gun violenceremaining statistically significant after accounting confounded socioeconomic resources (16,36). Although most research examining the associations between environmental conditions and corticolimbic function have focused on adverse childhood experiences, our results contribute to an emerging literature highlighting the power of promotive contexts (e.g., perceptions of social support) in shaping affective brain development (37,38).…”

Gun violence is a major public health problem and costs the United States $280 billion annually (1). Although adolescents are disproportionately impacted (e.g., via premature death), we know little about how close adolescents live to deadly gun violence incidents and whether such proximity impacts their socioemotional development (2–4). Moreover, gun violence is likely to shape youth developmental outcomes through biological processes – including functional connectivity within regions of the brain that support emotion processing, salience detection, and physiological stress responses – though little work has examined this hypothesis. Lastly, it is unclear if strong neighborhood social ties can buffer youth from the neurobehavioral effects of gun violence. Within a nationwide birth cohort of 3,444 youth (56% Black, 24% Hispanic) born in large U.S. cities, every additional exposure to a deadly gun violence incident within 500 meters of home in the prior year increased behavioral problems by 7.7%, even after accounting for area-level crime and socioeconomic resources. Incidents that occurred closer to a child’s home exerted larger effects, and stronger neighborhood social ties offset these associations. In a neuroimaging subsample (N = 164) of the larger cohort, exposure to more incidents of gun violence and weaker social ties were associated with weaker amygdala-prefrontal functional connectivity during socioemotional processing, a pattern previously linked to less effective emotion regulation. Results provide spatially-sensitive evidence for gun violence effects on adolescent behavior, a potential mechanism through which risk is biologically-embedded, and ways in which positive community factors offset ecological risk.

“…Changes in connectome in youth residing in socioeconomically disadvantaged areas suggest that neighbourhood deprivation impede the developmental progression of brain function in children and young adults (172), involving reduced fronto-amygdala and fronto-striatal resting state FC (173)(174)(175), and changes in FC between DMN and dorsal attention network and sensorimotor systems (166). The observed connectome alterations were coupled with internalising symptoms and worse cognition.…”

“…These discrepancies may be influenced by various factors, including the specific timing of exposure to community violence, developmental changes, individual characteristics, or other contextual factors, such as positive parenting and school environment (166,170,171). Differential social experiences, such as discrimination, within similar environments may exert distinct neural influences on minoritized and discriminated individuals, including various racial and gender identities, particularly in the domains of threat, reward and emotional processes (153,(172)(173)(174).…”

How does the macroenvironment influence brain and behaviour – a review of current status and future perspectives

The environment influences mental health, both detrimentally and beneficially. Current research has emphasized the individual psychosocial ‘microenvironment’. Less attention has been paid to ‘macro-environmental’ challenges including climate change, pollution, urbanicity and socioeconomic disparity. With the advent of large-scale big-data cohorts and an increasingly dense mapping of macroenvironmental parameters, we are now in a position to characterise the relation between macroenvironment, brain, and behaviour across different geographic and cultural locations globally. This review synthesises findings from recent epidemiological and neuroimaging studies, aiming to provide a comprehensive overview of the existing evidence between the macroenvironment and the structure and functions of the brain, with a particular emphasis on its implications for mental illness. We discuss putative underlying mechanisms and address the most common exposures of the macroenvironment. Finally, we identify critical areas for future research to enhance our understanding of the aetiology of mental illness and to inform effective interventions for healthier environments and mental health promotion.
