Linking structure and activity in nonlinear spiking networks
Fig 4
Diagrammatic expansion for the mean firing rate and linear response of the self-exciting process.
A) First-order approximation of the firing rate. B) Diagrams corresponding to the re-summing of the expansion of the mean field rate (Eq 25), which is represented by the black dot. C) Diagrams corresponding to the re-summing calculation of the propagator (Eq 28), which is represented by the solid edge. In all diagrams, time indices associated with internal vertices have been suppressed.
