The neurobiology of psychopathic traits in youths

Comprehensive review of neuroimaging evidence in youth with CU traits/ psychopathic traits. Consistent findings: reduced amygdala response to fearful faces, reduced ventromedial prefrontal cortex response to punishment cues, impaired reinforcement learning. Provides neurobiological grounding for the clinical observation that CU-positive children "don't seem to care" about punishment - empirically, their threat-processing system responds differently.
