Single compartmental, ball-and-stick models implemented in XPP and full morphological model in Neuron. Paper correlates anatomical properties with electrophysiological recordings from these hard-to-access neurons. For instance we make predictions about location of the spike initiation zone, channel distributions, and synaptic input parameters.

Follow the tutorial in the tutorial-replicate-paper-figure/ subdirectory README to get started with the model and replicate paper figures.
You can also use Python to work with the model in tutorial-python-neuron.

NeuroML2/ Ports of all models to NeuroML2 and LEMS. Includes OMV tests to check for consistency with the original models: Build Status.


Workflow/history of project:

  • Channel data were fit with the Neurofit tool and then re-adjusted with param-fitter in Matlab.
  • XPP models were built with these channels and hand-tuned to fit observed f-I, v-I, and delay.
  • Neuron model used these channels and some properties of the ball-and-stick model.
  • Morphological reconstruction passive parameters were tuned to recorded capacitance responses.
  • Channel distribution hand tuned to mimick observed current responses.
