Medial-prefrontal Enhancement During Schizophrenia Systems Imaging
Causal Role of Medial Prefrontal Neural Activity in Self-Agency in Schizophrenia

Conditions
Summary
This randomized controlled trial in healthy controls (HC) and patients with schizophrenia (SZ) aims to examine 1) the underlying cognitive and neural cause of self-agency deficits in SZ; 2) the responsiveness to a novel navigated repetitive transcranial magnetic stimulation (nrTMS) target in the medial/superior prefrontal cortex (mPFC); and 3) how modulation of mPFC activity impacts the larger self-agency network to mediate changes in self-agency judgments. Our overall hypothesis is that increased mPFC excitability by active high-frequency nrTMS in HC and SZ will induce behavioral improvements in self-agency and neural changes in the larger self-agency network that will generalize to improvements in overall cognition, symptoms and daily functioning, and will likely lead to the development of new effective neuromodulation therapies in patients with schizophrenia.
