property of nodes or clusters is to operate like temporal “shutters” that open and close at specific durations. Each Brodmann area maintains a different ratio of local vs. distant connections but nonetheless follows the general rule of an exponential decrease in local connections as a function of distance. This anatomical fact may explain the findings of discrete phase shift and lock duration due to unique local vs. distant excitatory connection densities in different Brodmann areas (Sporns, 2011).
