Targeting Large-scale Networks in Depression With Real-time fMRI (Functional Magnetic Resonance Imaging) Neurofeedback

Healthy subjects will complete two fMRI sessions after initial assessment and training in the Rest Focus Task (RFT). The first session will be the localizer session to identify the networks involved in switching in the RFT. The second fMRI session, real time functional magnetic resonance imaging neurofeedback (rtfMRI-NF) session, will use localizer information from the first fMRI session to develop a mask for the rtfMRI-NF, and deliver a neurofeedback (NF) stimulus while simultaneously measuring Blood Oxygenation Level Dependent (BOLD) activity for the STOP\>RECALL contrast.
