Anticorrelations between Active Brain Regions: An Agent-Based Model Simulation Study

Figure 5

Fitting empirical data by the ABM model: dependence upon model’s parameters. (a) Connectivity-dependent parameters (π_p and π_n) on the x-axis. Blue, green, and red lines indicate, respectively, nep values of 0.25, 0.50, and 0.75. (b) Cost (network density) parameter on the x-axis; sop and nep fixed at 0.025 and 0.225, respectively. Blue, green, red, and light-blue lines indicate, respectively, 0.1, 0.075, 0.05, and 0.025 values of π_p and π_n. Notice that a peak of the goodness-of-fit appears at π_p, π_n = 0.1, in the lower range only of the network density. In all cases, the Pearson correlation (r) is used as a goodness-of-fit index.
