Effect of mGluR2 receptor activated GIRK channel inhibition of Golgi cells on filter construction performance.

<p>For clarity only most affected target filter <i>τ</i>₃ = 500<i>ms</i> (red) is shown. Default synaptic time constants: <i>τ</i>_<i>w</i> = 50<i>ms</i>, <i>τ</i>_<i>u</i> = 1<i>ms</i>. <b>A,B</b>: Goodness of fit (<i>R</i>²) (<b>A1</b>) and Lyapunov exponents (<b>A2</b>) for default network (light red lines) and network with mGluR2 receptor activated GIRK channel inhibition of Golgi cells (<i>m</i> = 0.003) either without (<i>v</i>_<i>m</i> = 0) (dotted red lines) or small (<i>v</i>_<i>m</i> = 0.1) (dashed red lines) weight variability. Additionally results with mGluR2 dynamics in only 50% of the Golgi cells (solid red lines) (<i>Pr</i>(m = 0) = 0.5, <i>v</i>_<i>m</i> = 0.1). <b>B</b> shows results for networks without push-pull input coding.
