Relative sensitivity maps for the Early (A) and Late (B) models. AP features (rows) VS ratios RaI_xx (columns) used to rescale the maximum conductances/currents/fluxes were considered. For each RaI_xx the relative sensibilities at −20% and + 20% were taken into account. White color indicates maximum relative sensitivity of a particular AP feature among all ratios, whereas black indicates AP feature and ratio are independent. White X indicates the absence of spontaneous firing during a particular test. Percentages in each white box indicate the maximum absolute sensitivity of the AP feature correspondent to that row for all ratios. Negative sign indicates that AP feature and ratio vary inversely.
