Responses of constructed filters and individual granule cell rates.

<p><b>A,B,C</b>: Individual responses of randomly selected granule cells with weights <i>w</i> = 0.01 (<b>A</b>), <i>w</i> = 1.4 (<b>B</b>), <i>w</i> = 3 (<b>C</b>). Black bars indicate duration of pulse input. <b>D</b>,<b>E</b>: Responses of filters (<i>τ</i>₁ = 10<i>ms</i> (<b>D1</b>,<b>E1</b>), <i>τ</i>₂ = 100<i>ms</i> (<b>D2</b>,<b>E2</b>) and <i>τ</i>₃ = 500<i>ms</i> (<b>D3</b>,<b>E3</b>)) constructed from network with inhibitory time constant <i>τ</i>_<i>w</i> = 50<i>ms</i> and inhibitory weight <i>w</i> = 1.4 (blue, green and red lines), <i>w</i> = 3 (light blue, light green and light red lines) or <i>w</i> = 0.01 (dotted light blue, light green and light red lines) to colored noise input (<b>D</b>) or pulse input (<b>E</b>). Responses of corresponding ideal filters shown as black lines. To construct the shown filters of 10/100/500ms the percentage of weights equal 0 and mean absolute weights > 0 was 90/53/34% and 20.6/60.4/86.1 for <i>w</i> = 0.01, 76/70/65% and 4.2/13.6/26.5 for <i>w</i> = 3 and 91/86/75% and 5.5/11.7/52.6 for <i>w</i> = 1.4, respectively.
