Abstract

The relationship between cortical grey matter density and media violence exposure in healthy male adolescents was investigated using voxel-based morphometry and the Childrens' Report of Exposure to Violence. Adolescents with more frequent exposure have lower left lateral orbitofrontal cortex density—a possible risk factor for altered socioemotional functioning.
