Ventromedial prefrontal cortex is part of the prefrontal cortex that is responsible for processing risks and fears. Researchers believe that the use of transcranial magnetic stimulation (TMS) would be able to stimulation the circuitry. 25 participants with cocaine addiction and 24 participants with alcohol addictions volunteered to be in the experiment. Brain scans of the participants were taken when the participant was given a drug cue, which causes the patient to desire the drug. Then after receiving TMS the participants showed reduced activity when the drug was mentioned. The study is important because it provides evidence that addiction is partly a brain disorder.
