The role of the cerebellum in neurobiology of psychiatric disorders.

For a long time, cerebellum was only known for its role in movement coordination and until recently, its role in non-motor brain function was largely ignored. Recent evidences has expanded the concept of coordination, from voluntary movements and orientation of the body to nearly every cerebral function including emotion regulation, social cognition, and time perception. This article aims to review the current evidences supporting the role of the cerebellum in the pathophysiology of psychiatric disorders, including studies using volumetric and/or functional imaging techniques, genetic and molecular studies, and clinical reports. The implication of these findings, their potential use, and future directions are also discussed.
