摘要: Initially described as task-induced deactivations during goal-directed paradigms of high attentional load, the unresolved functionality default mode regions has long been assumed to interfere with task performance. However, recent evidence suggests a potential network involvement in fulfilling cognitive demands. We tested this hypothesis finger opposition paradigm and fixation periods which we compared an independent resting state scan using functional magnetic resonance imaging comprehensive analysis pipeline including activation, connectivity, behavioural graph theoretical assessments. The results indicate specific changes topography. Behaviourally, show that increased connectivity posterior cingulate cortex left superior frontal gyrus predicts faster reaction times. Moreover, interactive dynamic reconfiguration regions' connections illustrates their at hand higher-level global parallel processing power, yet preserved small-world architecture comparison rest. These findings demonstrate does not disengage paradigm, but instead may be involved relevant processing.
