For the large international DynaM-OBS and DynaM-INT studies, the participants’ brain activity is first scanned in the magnetic resonance imaging (MRI) scanner while performing various cognitive tasks. Study sites for these MRI scans are Berlin, Mainz, Warsaw, Nijmegen, and Tel Aviv. What happens in the MRI scanner? Which tasks are people subjected to, and why? How many people are participating? And what’s the procedure when coming in to do the scan? In this video, Dr. Ilya Veer, Dr. Carolin Wackerhagen, PhD student Antje Riepenhausen, and Master student Begüm Topaloglu are answering these questions!
