Study Summary

This will be a single site pilot study. 20 subjects with EPP (Early Phase Psychosis), defined as medical record documentation of the onset of clinically significant psychotic symptoms within the past 10 years, will be enrolled. Prior to randomization subjects will undergo fMRI (Functional Magnetic Resonance Imaging) during CC (Cognitive Control) task (Stroop Color-Word paradigm) and resting-state paradigms. This baseline scan will also include a high-resolution structural sequence for neuronavigation purposes. Then, on two separate days, each occurring one-week apart, subjects will receive one session of excitatory (20 Hz) (Hertz) rTMS (Repetitive Transcranial Magnetic Stimulation) targeting the LDLPFC (Left Dorsolateral Prefrontal Cortex) and one session targeting the LSPC (Left Superior Parietal Cortex). The order of stimulation sites will be randomized and counter-balanced. Immediately following each session, subjects will undergo repeat fMRI during CC and RS (Resting State) paradigms. Investigators will also examine the effect of rTMS on CC performance.

Primary Outcome

Effects of rTMS on anterior cingulate cortex functional activation as measured by blood oxygen level dependent (BOLD) signal change scores during cognitive control Mismatch trials vs. Match trials (i.e., Mismatch - Match). The BOLD signal is measured during a functional magnetic resonance imaging (fMRI) scan and reflects the level of brain activity in the region. Change is calculated as difference between the Mismatch-Match signal at baseline and 30-60 minutes following the intervention. Higher
