Stimulating Front Of Brain With Electricity May Cut Aggressive Urges: ‘It Sounds Like Pulp Fiction’ But It’s Not
The experiment, which zapped certain parts of the brain, found a 54 percent reduction in aggressive intentions in the group receiving the stimulation and a 31 percent jump in their sense of moral wrongfulness about acts of aggression.

Zapping The Brain Appears To Decrease Aggressive Intentions, New Study Says
The possibility of using brain stimulation to help prevent future violence just passed a proof of concept stage, according to new research published Monday in the Journal of Neuroscience. In a double-blind, randomized controlled study, a group of volunteers who received a charge to their dorsolateral prefrontal cortex — the part of the brain that lies directly behind the forehead and is responsible for planning, reasoning and inhibition were — were less likely to say they would consider engaging in aggressive behavior compared to a similar group that received a sham treatment.

Can Zapping Brains Reduce Violence? Controversial Study Sees Potential
The day before, half of them had had the frontmost region of their brains, responsible for such high-level functions as impulse control and moral judgments, electrically stimulated; the other half had not. The people whose prefrontal cortex was stimulated reported roughly half the likelihood of committing a violent act like the ones they watched, scientists at the University of Pennsylvania reported on Monday; they said they found such physical and sexual violence more morally wrong, compared with the control group.
