Social Neuroscience of Psychiatric Disorders is about the role of the Social Brain in neuropsychiatry. The need to belong to social groups and interact with others has driven much of the evolution of the human brain. The relatively young field of social neuroscience has made impressive strides towards clarifying the neural correlates of the Social Brain, but, until recently, has not focused on mental and neurological disorders. Yet, the Social Brain underlies all brain-behaviour disorders, and nearly every neuropsychiatric illness involves social behavioural disturbances.
