With brain scans you can set the probability of drug addiction

Early it was known that adolescents who achieve the highest test results in search of novelty, often prone to substance use. However, experts from the University medical center Hamburg – Eppendorf and Stanford University are convinced that there is a new test that is able much better determine risk propensities, as stated in the Zee News.

The experiment involved 140 fourteen-year-old teenager who had not previously used drugs, but during testing in search of novelty have shown good results. Adolescents in the experiment, MRI was done. During this procedure, they played video games. The participants could earn points, which later had to transfer the money.

At the end of each round, the teenagers were told how many points they can score in the next round. Thus players start to anticipate the amount of future gains. The researchers monitored areas of the brain responsible for emotion associated with the award. In anticipation of a reward, most people have activated a specific brain system.

The brain of a child on a stimulant, basically, responds not as much as the adult brain. However, in subjects who are prone to taking drugs, this activity is still less. It is not excluded that drugs tend to suppress the brain activity that is associated with the reward. Or, to use drugs adolescents pushes the low activity of the brain.
