This is the top level readme for the NEURON models associated with the paper: Hsu CL, Zhao X, Milstein AD, Spruston N (2018) Persistent sodium current mediates the steep voltage dependence of spatial coding in hippocampal pyramidal neurons. Neuron 99, 1–16 These models were based on previously published models (as described in the paper). The simulations serve as independent tests for the proposed mechanism underlying the synaptic amplification observed in our experiments. These models require that the NEURON simulation environment is installed, which is freely available from http://neuron.yale.edu To run the simple model see the instructions in the readme in the SimpleModel folder, and for the full model (which is also available at the github repo https://github.com /neurosutras/nap) see the readme in the FullModel folder. These models were contributed by Ching-Lung Hsu (hsuc@janelia.hhmi.org) and Aaron Milstein (aaronmil@stanford.edu). 20180615 An update from Aaron Milstein for the FullModel folder where the three python scripts for generating figures take in the required .hdf5 file paths as command line arguments, e.g.: python plot_nap_EPSC_amplification data/20180220_nap_EPSC_amplification_soma.hdf5 # generates plots similar to Figure S5 python plot_nap_EPSP_amplification data/07162017_nap_amplification_DC_soma_stim_trunk.hdf5 data/07162017_nap_amplification_DC_dend_stim_trunk.hdf5 # generates plots similar to Figure 5C and S4 python plot_nap_EPSP_amplification_IO data/08112017_nap_amplification_IO_DC_soma_stim_trunk.hdf5 # generates plots similar to Figure 6B
