Abstract

The purpose of this study was to determine where in the brain there may be a difference in brain activity in patients during their first episode of psychosis (FEP) compared to healthy controls (HCs) while performing an auditory oddball task. Time-frequency analysis allows for spectral decomposition where the signal measured by magnetoencephalography (MEG) is used to characterize changes in neural oscillations and their synchronization over time and region. Previous EEG studies report reduced alpha (8-12Hz, 70-160ms) power but most studies focused on patients with chronic schizophrenia and with limited source localization.
