Researchers at the U.S Department of Energy’s Brookhaven National Laboratory have literally been able to get into the mind. they have developed a system which is able to visualise the rewards mechanism of the brain and how it works in addicts and non addicts. this way, they can understand the reason for the addictions and how best to treat them.Various factors influence the decision to take drugs. The basic effect it has on Dopamine is what is of interest to the researchers. the scientists have used a combination of positron emmission tomography along with special radioactive tracers. these tracers bind with the dopamine receptors and this gives us an idea of where they are going and which sites they are energising. this helps in understanding how they are working and where they need to be controlled.

Some times the dopamine response is effected too in the addicts due to which they get addicted to higher usage of drugs to stimulate themselves.
