The Correlation Structure of Local Neuronal Networks Intrinsically Results from Recurrent Dynamics

Figure 8

Connectivity structure determines correlation structure.

In the left column (A,C,E) is the independent variable, in the right column (B,D,F) . A,B Mean activity in the network as a function of the structural parameters and , respectively. C,D Correlations averaged over pairs of neurons. Dots obtained from direct simulation, solid curves given by theory (24) E,F Eigenvalues (30) of the population-averaged connectivity matrix; solid curves show the real part, dashed curves the imaginary part.
