Dr. Mennemeier, the director of the Transcranial Magnetic Stimulation Laboratory in the Center for Translational Neuroscience has been using repetitive transcranial magnetic stimulation (rTMS) to understand and treat phantom sound perception in subjects with tinnitus and to examine risky choices and impulsive behaviors using delay discounting in smokers. We propose to replicate a randomized controlled trial of rTMS over 3 days in a sample of well characterized acutely suicidal inpatients.
