Abstract: | For about two decades now, the localization of the brain regions involved in reasoning processes is being investigated through
fMRI studies, and it is known that for a transitive form of reasoning the frontal and parietal regions are most active. In
contrast, less is known about the information exchange during the performance of such complex tasks. In this study, the propagation
of brain activity during a transitive reasoning task was investigated and compared to the propagation during a simple memory
task. We studied EEG transmission patterns obtained for physiological indicators of brain activity and determined whether
there are frequency bands specifically related to this type of cognitive operations. The analysis was performed by means of
the directed transfer function. The transmission patterns were determined in the theta, alpha and gamma bands. The results
show stronger transmissions in theta and alpha bands from frontal to parietal as well as within frontal regions in reasoning
trials comparing to memory trials. The increase in theta and alpha transmissions was accompanied by flows in gamma band from
right posterior to left posterior and anterior sites. These results are consistent with previous neuroimaging (fMRI) data
concerning fronto-parietal regions involvement in reasoning and working memory processes and also provide new evidence for
the executive role of frontal theta waves in organizing the cognition. |
