Advances in physics, computing, and signal processing have provided a range of computerized brain imaging technologies that facilitate examination of the brain as a dynamical system. This article provides a review of brain imaging advances and their application in neuropsychiatry. The review encompasses (1) a description of the imaging technologies used in neuropsychiatry; (2) an outline of their temporospatial complementarity; (3) application to clinical applications; and (4) suggested future directions including an "integrative neuroscience" approach to neuropsychiatry (in which theoretical models, data and information concerning mechanisms are integrated). In the absence of a unified theory of the brain, an integrated approach is presented as one means of exploring converging brain-imaging evidence in relation to neuropsychiatric disorders.
