Network Control TMS fMRI

Study Overview

The University of Pennsylvania seeks young adults ages 18-28 for a research study. The purpose of this study is to use different types of MRI scans to find individualized TMS (transcranial magnetic stimulation) targets and compare how the brain responds. We are also interested in using TMS during a working memory test to see how it affects task performance. TMS involves a procedure during which your brain will be noninvasively (i.e. from the scalp) stimulated by magnetic pulses and MRI scans are used to take pictures of your brain. In this study we administer TMS inside of the MRI scanner so we can see how the stimulation affects the rest of the brain.
