The secret of people who are easily tempted

A study shows that the human brain has both 'good' and 'bad' areas. Each time faced with temptation, the 'good' area of ​​the person with the more active nature. But in people without bravery, the situation takes place in the opposite direction.

For many years, experts in the field of economics, psychology, and religion always concern with the question: Why can some people control themselves very well when faced with temptation, while many people Other can not do the same thing?

Dr. Antonio Rangel, a neurologist at the California Institute of Technology (USA), said: 'From the perspective of modern neuroscience, we want to understand the differences in the brains of people who always behave correctly. good for those who are easy to commit wrong behavior '.

Dr. Rangel's team asked the volunteers to fast and show them pictures of 50 types of food (chocolate candy, cauliflower, corn .). Experts require volunteers to rank food according to two criteria: taste and nutrient content. After that, each volunteer must choose a food that they consider to be beneficial to health

In the next test, the team asked volunteers to choose between healthy foods and other foods. Scientists take a brain scan of volunteers while they make decisions. The results showed that the cerebral plexus of the anterior roof and the medial lobe of the forehead had a completely different type of activity.

If the signal in the frontal brain area is stronger, volunteers will choose healthy food whether they are tasty or have low nutritional content. Conversely, when the signal in the shell of the middle forehead is stronger, they only choose food that has an attractive taste despite knowing that it is harmful to health.

'After centuries of controversy, we finally understood the brain's self-control mechanism when we face temptation. We will conduct more tests to better understand how to control behavior for different types of temptations , 'said Professor Colin Camerer, a member of the research team.

The team hopes that the finding will help them find ways to treat those who can't control themselves.
