Research Synopsis

The primary focus of Dr. Graff’s research aims to describe the abnormal neurobiological mechanisms present in schizophrenia, as well as the characterization of biological markers for diagnosis and for prediction of response to treatment. Dr. Graff employs a multimodal neuroimaging approach, including Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MRI, fMRI and MRS). PET and MRS allow exploring the ‘brain neurochemistry’ in vivo; fMRI explores the ‘neuronal function;’ and MRI explores the ‘brain structure.’
