Figure 8.

(A) Variance in the position of the bump in the first area 〈Δ₁(t)²〉 builds up more slowly in networks with more areas N, and we expect similar behavior in all other areas. Fixing the strength of interareal connections, $\sqrt{\epsilon }{w}_{jk}(x)=0.01(\cos (x)+1)$ for j ≠ k, we see that varying N decreases the variance 〈Δ_j(t)²〉. (B) As in dual area networks, increasing the level of noise correlations between areas diminishes the effectiveness of interareal connectivity as a noise cancelation mechanism. Other parameters are as in Figure 2.
