The study of structural and functional connectivity (SC,FC) and dynamics in spontaneous brain activity is a rapidly growing field of research . The existence of Resting State Networks (RSN) has been well established in fMRI over the past decade,  and computational models  have successfully captured their connectivity patterns and slow oscillations, but have not been applied to recent MEG findings of coherent RSN  yet.
In the presence of noisy oscillations on the same order of magnitude as system delays, the temporal connectivity structure plays a role in shaping the functional network connectivity. By effectively decreasing strong synchronous inputs to nodes, the network is stabilized and the need for fine-tuning of global coupling reduced when compared to the absence of delays.
