Figure 12. Mean field amplitude landscapes of complete and reduced populations of Hindmarsh-Rose neurons.
Comparison between contour maps of the mean field amplitude obtained using the entire population (upper row) and the reduced system (middle row) for different values of the inhibition/excitation ratio n and the mean m of membrane excitability distribution. Every map is displayed as a function of the connectivity strengths K 11, K 12 and the magnitude of dispersion σ. The corresponding surfaces of absolute error (AE) are presented on the bottom row. The values of the normalized mean error (NMAE) calculated for every scenario are: (A) 12.89%, (B) 19.63%, (C) 13.44%, (D) 42.63%.
