Before revision:  Direct simulations are used to determine the similarity of functional (inferred from correlated activity between brain areas ) and structural connectivity matrices as a function of the parameters controlling dynamics of a single node , highlighting a non-trivial structure--function relationship in regimes that support limit cycle oscillations.
