title: Raven's Progressive Matrices in the Lexicon of Dynamic Mapping of the Brain (MRI).
abstract: Using functional magnetic resonance imaging, we studied intracerebral dynamics during completion of Raven's Progressive Matrices test. Solving the test organized in sets of progressively increasing difficulty cause changes in cerebellar activation functionally related to cognitive activities and operations. As the tasks became more complicated, we observed gradual suppression of the activity of default mode network (DMN). The most pronounced changes in cerebral activation patterns occurred the second set of the test and involved associative somatosensory area and Wernicke's area that is known to play an important role in cognitive processes associated with synthesis and analysis of information.
