I want to model a regular spiking basket cell in NEURON. Of course there is a lot of ion-currents, that are involved here, but I am searching for the minimal amount of ionic currents that can describe this cell, with a fairly good approximation. I would be grateful if someone could advise me on this subject with the names of the currents (such as Ia -the A-type potassium current.... etc) that are enough to model this cell. And also, how do these parameters depend on the morphology of the cell, besides the density. Is it enough to have a standard ionic current, and insert it to a reconstructed cell, or is it crucial to have these currents from the cell, where the model came from?
