Representation of the relative errors in the IAHP and ILTS dominance phases. The pair of figures shows the relative error (dashed red), the estimated value (dotted black) and the actual value (solid black) of the synaptic, excitatory and inhibitory conductances, respectively, in the subthreshold regime. Vertical lines show the border between the IAHP-dominance (left) and ILTS-dominance (right) phases. The curves have been smoothed for a clearer plot. The actual values can be found in Table 1.
