Reservoir Computing Properties of Neural Dynamics in Prefrontal Cortex

Mixed selectivity and performance of the model as a function of noise.
Each curve represents the average ratio of model units that are significant for one of the tests. Tests include selectivity for factors Choice, Phase, and the interactions Phase-Choice, Epoch-Phase, Epoch-Choice, Epoch-Phase-Choice (3-way ANOVA, Epoch x Phase x Choice, shaded areas correspond to standard error). For comparison purposes, the dACC ratios are plotted as dashed lines with the same color code (see legend). On a similar scale is represented the performance of the model (black line) as the ratio of trials with a correct answer over the total number of trials. All selectivity ratios decreased with increasing noise, more complex selectivities decreasing faster. As dynamic mixed selectivity dropped with the slightest noise, so did the performance.
