Sieci spoczynkowe i ich rola w zrozumieniu organizacji funkcjonalnej mózgu

Functional magnetic resonance imaging revealed slow, spontaneous fluctuations of BOLD signal, which were synchronized between various distant brain areas. These patterns of synchronization were used to attribute brain regions into ?resting state networks? also known as ?intrinsic connectivity networks?, which exhibited highly correlated activity independently from current, on-going tasks. The present review describes the most important functional networks invoked in neuroimaging studies together with methods for their identification, evidence for their neuronal underpinnings and the principles of their cortical organization. Finally, I discuss how the discovery of brain functional systems impacts neuroscientific studies of cognitive functions in health and disease.
