Effects of psychological intervention on brain activity - an approach to mechanisms?

Functional brain activity measured in experimental tasks (designed to activate a specific psychological process) is commonly understood as reflecting the brain's code, the mechanism underlying or enabling the respective psychological function - but what we measure are correlative links, which do not justify directional conclusions. Modification of one variable in the correlative link by training and measure related changes of the other variable may be a complementary test of support of the hypotheses about mechanisms relating neuronal and functional levels. I will describe the effects of psychological intervention (computer-assisted training protocols that targeted cognitive deficits in schizophrenia patients and considered principles of neuroplasticity) on event-related and oscillatory neuromagnetic responses in order to discuss, whether training effects on evoked and induced oscillatory activity improve our understanding of brain mechanisms of cognitive function and dysfunction in schizophrenia.
