Whole brain functional connectivity: Insights from next generation neural mass modelling incorporating electrical synapses
Fig 3
Exemplar proxy FC computed from eigenvectors of the structural connectivity matrix wij, computed by taking the outer product of an eigenvector with itself.
Panels (A-F) show FC matrices constructed in this way from structural eigenmodes that correspond to the largest six eigenvalues, ordered by decreasing size. Visualisations on a cortical surface are coloured according to the value of normalised eigenvector components, with warmer colours indicating higher values.
