Fig 7. Effects of Golgi cell afferent excitation on filter construction performance.

As previously, target filters used are τ ₁ = 10ms (blue), τ ₂ = 100ms (green) and τ ₃ = 500ms (red). Default synaptic time constants: τ _w = 50ms, τ _u = 1ms. A,B: Goodness of fit (R ²) (A1,B1) and Lyapunov exponents (A2,B2) for default network (light lines) and network with external excitation of Golgi cells (dark lines) with either default excitation of u = 0.1 (A) or increased excitation u = 50 (B).
