Structure-Function Discrepancy: Inhomogeneity and Delays in Synchronized Neural Networks
Figure 8
Anatomical connectivity matrix and resulting functional connectivities as a function of delay distribution.
A: Sparse neuroanatomical coupling matrix serving as structural connectivity (connections are given in yellow). B: Structure-function correlation
. C: Overall synchronizability
. Between-pair coupling strength
appears on the horizontal axis; while blue, red, and black lines correspond to
respectively. Note that an increase in delay distribution width increased synchronizability due to increased
, but the accompanying higher
variance decreased structure-function correspondence as predicted by (3). D-F: Corresponding spatial synchronization matrices
