README In Figure 3 we have used an active model for a human L2/3 neuron to demonstrate the effect of low Cm value on signal transfer and cortical computations. We have used the model from Fig. 1a, to which we added a simplified excitable model for the generation of Na+ spikes at the soma. We aimed at preserving both the current threshold (~300 pA) and the voltage threshold (~ + 20 mV above resting potential) for spike initiation as found in in vitro experiments in these cells (Verhoog et al. 2013; Testa-Silva et al. 2014) The model is available under ActiveModels/model_0603_cell08_cm045.hoc The other model model in this directory is the same model but with Cm=0.9 : model_0603_cell08_cm09.hoc In order to run the simulations in this directory (Fig3a, Fig3b and Fig3a), you will have first to compile the three mechanisms in the mechanisms folder (na, kv and NMDA).
