Aggression posed by violent individuals is a major public health concern and to date, interventions to reduce aggression are found to be insufficient in doing just that. Aggressive behavior is associated with dysfunctions in the prefrontal cortex, of which the Dorsolateral Prefrontal Cortex (DLPFC) and Ventromedial Prefrontal Cortex (vmPFC) are two of the most studied areas. There has been a growing interest in using Transcranial Direct Current Stimulation (tDCS) as an intervention to modulate brain regions of interest and increasing activity in damaged brain areas that show blunted activity.In this presentation, I will discuss the current state-of-the-art with respect to studies on tDCS and aggression. Moreover, I will discuss our recent findings that have not only shown that tDCS can be effectively used to modulate brain activity and aggression, it also has shown that it is effective in increasing synchronization of neural activity in the brain of violent offenders.
