OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Understanding how environmental factors—at the individual, neighbourhood, and societal levels—shape brain and behaviour development
Understanding typical and atypical neurodevelopment requires attention to the full ecology in which children grow. Anchored in Bronfenbrenner’s ecological framework, this talk will present findings from neuroimaging studies that examine how environmental factors—at the individual, neighbourhood, and societal levels—shape brain and behaviour development.
I will first describe work demonstrating how individual-level contexts—including family socioeconomic resources and childhood adversity such as maltreatment—shape trajectories of structural and functional development to ultimately contribute to differences in cognitive and socio-emotional outcomes. Moving beyond the family, I will highlight evidence that neighbourhood characteristics, including deprivation and access to green spaces, confer independent effects on the brain and behaviour, and that these associations depend on other aspects of children’s environments. In particular, I show that positive parenting practices and school environments can buffer the effects of neighbourhood disadvantage on the brain, and that different dimensions of SES jointly shape brain structure and function. Finally, I present new findings that structural factors—namely macroeconomic income inequality—have widespread effects on cortical thickness, surface area, and functional connectivity, even after accounting for individual- and state-level confounders. These neural alterations partially account for elevated risk for later mental health problems among children living in more unequal states.
Together, this work demonstrates how environmental influences across multiple levels contribute—independently and jointly—to differences in children’s brain development. Findings underscore the need for policies that strengthen family and school supports, invest in neighbourhoods, and address structural inequality to promote healthy developmental trajectories.
