AI-Summary

What this Trial Is About

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.
