An eLIF model using a Δ_<i>T</i> value of 15 mV generates limited modulation of input-output responses by membrane voltage fluctuations.

<p>(A) Example traces of eLIF models implemented with Δ_<i>T</i> = 15 mV (i) and 2 mV (ii). (B) <i>f-I</i> curves in eLIF models with Δ_<i>T</i> = 15 mV (i) and 2 mV (ii) with or without membrane voltage fluctuations under baseline (black) or increased membrane conductance (<i>g</i>_<i>shunt</i>-grey). (C) Spike-probability curves in eLIF models with Δ_<i>T</i> = 15 mV (i) and 2 mV (ii) with or without membrane voltage fluctuations under baseline (black) or increased membrane conductance (<i>g</i>_<i>shunt</i>-grey). (D) Changes in firing rate induced by membrane voltage fluctuations for low, mid and high regions of the <i>f-I</i> curves for each model. For comparison, average stellate cell values are also shown. (E) Plots of changes in rheobase (i) and sigmoid slope factor (ii) in spike-probability measures associated with the introduction of membrane voltage fluctuations for each model.
