Brain Function in Schizophrenia: Discussion

  • A. Öhman


Talk about the light at the end of the tunnel often turns out to be mistaken. Nevertheless, with regard to brain functions in schizophrenia, breakthroughs can be anticipated, since many of the conditions for rapid progress appear to be met at the present time. First, we have in our hands a new set of tools which for the first time allows quite detailed imaging of the working brain, as it is engaged in psychologically meaningful activities. Dr. Wiesel in his paper, has provided us with some interesting glimpses of what these techniques are starting to reveal about brain functions in schizophrenia. Second, cognitive science offers new techniques to break task performance down into its detailed, fundamental components, which can then be related to specific areas of the brain. Particularly the work of Posner and colleagues (Petersen et al. 1988; Posner et al. 1987; 1988a, b, c) shows exciting promise for a novel understanding of the relationships between cognitive operations and the human brain. Third, the new imaging techniques and the developments in cognitive sciences jointly have brought a new vitality to clinical neuropsychology, which now has access to a series of techniques to assess functions that can be differentially related to brain structures. These developments have been skillfully used in the research that Dr. Gruzelier reviews in his contribution. Fourth, during the last decade systematic bodies of knowledge about schizophrenia have been developed.
