The Clinical Neurophysiology Research Laboratory’s program of research focuses on understanding the pathology and pathophysiology of first episode psychosis and the progressive course of structural and functional impairments early in disease course. Understanding of the basic dysfunctions will, in turn, lead to earlier identification, better interventions, and improved outcome in schizophrenia and other psychotic disorders. The objectives of this work are to: 1) Understand the brain abnormalities that give rise to psychosis by focusing on structural and functional abnormalities that can be tied to specific symptom constellations; 2) Track progressive changes in brain structure and function during the early disease course and relate such changes to the evolution and trajectory of clinical symptoms; 3) Develop simple to administer neurophysiological tests for deployment into clinical high risk samples as biomarkers of psychosis; and 4) Develop translational measures of simple cognitive and sensory processes that can be applied to animal models to understand the basic underlying cortical circuitry. Dr Salisbury’s laboratory utilizes multimodal imaging of neurophysiology (EEG, MEG), hemodynamics (MRI), and anatomy (MRI) in service of realizing these objectives by capitalizing on the outstanding infrastructure for integrated clinical care and research studies for first episode psychosis at WPIC.
