Abstract
Electroencephalography (EEG) has garnered increasing attention as a tool for translational research aiming to integrate clinical and basic research insights, offering optimal detection and evaluation of dynamic neural activity deficits in mental disorders. With a rich history in psychiatric research, including recent studies on neural oscillations, EEG research in psychiatric disorders, particularly focused on schizophrenia, has accumulated substantial neurophysiological evidence that could serve as biomarkers. However, owing to the heterogeneity inherent in schizophrenia, applications for diagnosis and treatment remain limited. In this review, we present the significance, current challenges and practical initiatives of a nationwide collaborative multi‐facility clinical EEG research project launched in 2020. Recently, each participating facility has established a framework for conducting research tailored to its characteristics, enabling the collection of transdiagnostic EEG data. Moreover, standardized measurement environments across all facilities and centralized database management have facilitated uniform and high‐quality data collection, supported by interdisciplinary analysis teams for advanced data processing. This collaborative research framework is expected to propel the advancement of neurophysiological investigations in psychiatric disorders, with a particular emphasis on clinical applications.
