Fig 8. Computational capability of the network.
Characterization of the firing activity of the network, obtained as response to three consecutive inputs presented in succession. a) Percentage of the variance of the neuronal firing activity reproduced by each of the first 10 principal components. The inset displays the corresponding cumulative percentage as a function of the considered component. Filled black and shaded red (bar or symbols) correspond to τα = 20 ms and τα = 2 ms, respectively. Projection of the neuronal response along the first three principal components for b) τα = 20 ms and c) τα = 2 ms. Each point in the graph correspond to a different time of observation. The three colors denote the response to the three different inputs, which are quenched stimulation currents randomly taken as I(j) ∈ [Vth, Vth + ΔV] for j = 1, 2, 3, the experiment is then performed as explained in the text.
