Extract

Over the past several years there has emerged a family of highly sophisticated but technically complex procedures for the visualisation of a range of cerebral functions in living man (Andreasen, 1988). The images they produce are so beguiling not just because of their potential to give new insights into the pathophysiology and treatment of major psychiatric disorders, but because they convey information through a quite fundamental modality: people are only convinced by what they can see. However, initial applications of such new technology have appeared just as likely to generate new questions and contradictions as to provide answers to current issues. This is readily illustrated by recent studies on the imaging of brain dopamine receptors in schizophrenic patients by positron emission tomography (PET) (see Waddington, 1989a).
