and has been associated with poorer cognitive performance and increased risk for psychiatric illnesses,
including PTSD. However, no study to date has investigated the neural correlates of
community violence exposure in adolescents. Sixty-five healthy adolescents (age514–18 years;
36 females, 29 males) from moderate- to high-crime neighborhoods in Los Angeles reported their
violence exposure, parents’ education level, and free/reduced school lunch status (socio-economic
status, SES), and underwent structural neuroimaging and intelligence testing. Violence exposure
negatively correlated with measures of SES, IQ, and gray matter volume. Above and beyond the
effect of SES, violence exposure negatively correlated with IQ and with gray matter volume in the
left inferior frontal gyrus and anterior cingulate cortex, regions involved in high-level cognitive
functions and autonomic modulation, and previously shown to be reduced in PTSD and combatexposed
military populations. The current results provide first evidence that frontal brain regions
involved in cognition and affect appear to be selectively affected by exposure to community violence,
even in healthy nondelinquent adolescents who are not the direct victims or perpetrators of
violence.

emotional brain functioning. Most recently, these differences
have been extended to include cultural effects on the real-time
neural correlates of social–emotional feelings. Here we review
these findings and use them to illustrate a biopsychosocial
framework for studying acculturated social-affective
functioning and development. We argue that understanding
cultural differences in emotion neurobiology requires probing
their social origins and connection with individuals’ subjective,
lived experiences. We suggest that an interdisciplinary,
developmental perspective would advance scientific
understanding by enabling the invention of protocols aligning
neurobiological measures with techniques for documenting
cultural contexts, social relationships and subjective
experiences. Such work would also facilitate insights in applied
fields struggling to accommodate cultural variation, such as
psychiatry and education.
