Functional neuroimaging of cognition: state-of-the-art.

This paper presents a brief overview of functional neuroimaging studies of cognitive processes. A "publication profile" is identified for PET and fMRI studies of cognitive functions. It is shown that the number of publications has increased exponentially over the last ten years, and that a set of ten journals accounts for the vast majority of publications. It is argued that the field has moved from a state of explorative character to a state of high theoretical sophistication. With special reference to the contributions in this issue of Scandinavian Journal of Psychology, methodological, topical, regional, and clinical implications of cognitive neuroscientific studies are discussed.
