Distribution of end of delay period activity for a line attractor and two instances of the decay and amplify model.

<p>The first row shows the distributions for a line attractor. The second and third rows show the distributions for models with decay rates of (), and (), respectively. The corresponding amplification rates are also and . The distributions in a single column are very similar, demonstrating that the decay and amplify mechanism integrates noise no better or worse than a line attractor.
