Lower lateral orbitofrontal cortex density associated with more frequent exposure to television and movie violence in male adolescents.

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.
