Transcranial magnetic stimulation (TMS) is a noninvasive treatment that uses pulses of magnetic fields to stimulate nerve cells in the brain. These magnetic pulses can increase activity or decrease activity in certain areas of the brain leading to potentially therapeutic results for certain disorders. Since 2008, it has been approved to for the treatment of depression and is generally used in individuals who have not had success in treatment with medications or therapy. It has also been FDA approved for the treatment of migraines since 2013. In the Hanlon Lab, we are examining how using TMS to stimulate various neural networks in the brain might be beneficial to reduce craving for substances of abuse including alcohol, cocaine, opiates, and nicotine. We are also examining how using various types of TMS might be more beneficial to helping individuals achieve and maintain abstinence.
