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.

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.
