Electroencephalogram (EEG) can be used to quantify the synchronisation of neural populations that make up such large scale networks. For example, during resting EEG, alpha (8-12Hz) and theta (4-7.5Hz) band activity are emerging as indexes of functional connectivity, with stronger alpha and lower theta power indicating increased neural synchronisation across the cortex. Increased neural synchronisation is likely to be a marker of more efficient functional connectivity. Hence, higher order cognitive processes that require efficient integration of information are likely to be performed faster and/or more accurately by individuals with stronger resting state synchronisation across networks. Cognitive flexibility, i.e., the ability to flexibly adapt behaviour to meet changing goals, is a cognitive control process that requires information integration across networks. In this study, we investigate the relationship between functional connectivity and cognitive flexibility. We measure alpha and theta power during eyes-closed resting state EEG before, during and after performance of a cognitively demanding task switching paradigm. We examined whether variability in alpha and theta power measures was related to variability in switching efficiency in a group of 20 young adults. Early findings suggest that individual variability in functional connectivity is related to variability in cognitive control efficiency. These differences may reflect variability in information processing within frontal processing networks.
