Brain wave stimulation helps limit crime?

Scientists have suggested a shocking method to limit crime in the future: stimulating brain waves.

Professor Olivia Choy, a psychologist at Nayang University of Technology, Singapore, said that previously neuroscientists had known the decline of the prefrontal cortex in relation to antisocial behaviors but it was unclear. Is this region's weak activity related to violent activities?

"We want to find out if there is a connection , " Professor Olivia Choy told The Guardian.

Professor Olivia Choy and Adrian Raine and Roy Hamilton of the University of Pennsylvania, USA recruited 86 volunteers, and in turn, stimulated the brain of half of the group within 20 minutes by 2mmA electric current.

Later, the team showed two volunteers a scene of two scenes: a very fierce bottle fight scene, a night rape scene. When finished watching, the volunteers were asked to rate the level of interest if they became the main role of the film.

As a result, brainwave processors reduced 47% of the first scene interest and reduced the love of the second scene. These numbers are much lower than those who do not stimulate brain waves.

The study was published in the Journal of Neuroscience. Professor Olivia Choy said from the above results, we can see that brain stimulation has affected more or less to reduce a person's liking to violent things.

However, Caroline Di Bernardi Luft, a psychologist at the University of London, UK, said that because the research team has not done on the offenders themselves, it is difficult to prove that stimulating the brain can reduce crime in real life. is not.

The team also said that more research is needed to determine exactly how stimulating it is, how much intensity is just enough to influence people's perception of good and evil.

If really effective, Adrian Raine believes that countries can use the above method to limit crime in the future. This modern way will be much better than traditional methods such as propaganda or teaching .
