Bilateral Prefrontal Cortex Anodal tDCS Effects on Self-reported Aggressiveness in Imprisoned Violent Offenders

Reduced activity of the frontal lobes, and particularly of the prefrontal cortex, has been related with violent behavior, aggression and crime. The causal importance of prefrontal cortex activity for aggressive behaviors and the self-perception of aggressiveness needs however to be clarified. The ai...
