Bump position variance depends non-monotonically on asymmetric connectivity strength. (A) For κ₂ = 0.01 and high enough values of coupling (κ₁ = 0.05), variance 〈Δ₁(t)²〉 scales more quickly than for symmetric coupling (κ₁ = 0.01). Layer 1 is being sourced by the noisier area 2. (B) Non-monotonic dependence of variance 〈Δ₁(t)²〉 on projection strength from area 2 to area 1 κ₁ is shown for fixed time T = 50 and κ₂ = 0.01 fixed. Amplitude of noise in area 2 is twice that of area 1 (c₁ = 1 and c₂ = 2). Other constituent functions and parameters are the same as in Figure 2.
