Based on the Layer 5 thick-tufted pyramidal cell from the Blue Brain Project, we modify the distribution of the sodium channel Nav1.2 to recapitulate an increase in excitability observed in ex vivo slice experiments.

# Scn2a Compartmental Model

Models and Jupyter notebooks for:

** Paper reference **

The simulations were tested with:

- Python v3.8.5

- NEURON v8.0

Model in ./Na12 Analysis/NaV12_analysis.ipynb corresponds to Figure 3, S3A-B, S4.

Model in ./Ri Increase/25% Ri Increase Figures.ipynb corresponds to Figure S3C.

Compile in mechanisms folder by running shell command `nrnivmodl` (Mac)/`mknrndll` (Windows) and copy x86_64 folder (Mac)/nrnmech.dll (Windows) to model folder.
