Association of Childhood Violence Exposure With Adolescent Neural Network Density

Childhood violence exposure and social deprivation are likely to affect later functioning of neural brain circuits. In a functional magnetic resonance imaging study of US adolescents, those with high violence exposure were more likely to have few shared neural connections and lower network density. This video illustrates individual connectivity maps in study participants. Red connections have positive β weights and blue connections have negative β weights. Solid connections are contemporaneous and dashed connections are lagged. V1 indicates left amygdala; V2, left dorsal anterior cingulate cortex (dACC); V3, dorsolateral prefrontal cortex (dlPFC); V4, left insula; V5, left inferior parietal lobule (IPL); V6, left medial temporal gyrus (MTG); V7, left posterior cingulate cortex; V8, right amygdala; V9, right dACC; V10, right dlPFC; V11, right insula; V12, right IPL; V13, right MTG; V14, right PCC.
