At the Edge of Chaos: How Cerebellar Granular Layer Network Dynamics Can Provide the Basis for Temporal Filters
Fig 8
Effect of mGluR2 receptor activated GIRK channel inhibition of Golgi cells on filter construction performance.
For clarity only most affected target filter τ3 = 500ms (red) is shown. Default synaptic time constants: τw = 50ms, τu = 1ms. A,B: Goodness of fit (R2) (A1) and Lyapunov exponents (A2) for default network (light red lines) and network with mGluR2 receptor activated GIRK channel inhibition of Golgi cells (m = 0.003) either without (vm = 0) (dotted red lines) or small (vm = 0.1) (dashed red lines) weight variability. Additionally results with mGluR2 dynamics in only 50% of the Golgi cells (solid red lines) (Pr(m = 0) = 0.5, vm = 0.1). B shows results for networks without push-pull input coding.
