I use the neuron models published by the BBP and available on this portal.
I noticed that some of them show spontaneous firing when including the complete axon while they do not when implementing the stub axon instead.
It happens mostly for cNAC and dNAC neurons.
It is puzzling however that in neurons sharing the same biophysics file (for example one neuron type with 5 different morphologies), some display spontaneous firing while other do not, suggesting that the morphology is critically involved (I believe that is the only variable differing between them).
Is that correct? Or have I again coded a bug? It is anyway quite easy to reproduce (for example: 'L23_SBC_dNAC222_3' shows spontaneous firing while 'L23_SBC_dNAC222_2' does not (with the complete axon)).
Should the neuron models be used with the complete axon? I am interested in the response of these neurons to various extracellular stimulations. How the implementation of the complete axon can produce such a change?
