Not a waste of time at all. These discussions become part of the available documentation,
and very often address issues that haven't been covered elsewhere.

Correct. A class definition that is written by the CellBuilder includes a public
procedure called position() that can be used to specify the location of any
cell instance. For example,
procedure called position() that can be used to specify the location of any
cell instance. For example,
Code: Select all
objref pyr4
pyr4 = new L4pyr()
pyr4.position(10, 20, 30) // desired coords of 0 end of root section (soma)

The first and most important tool for reducing model complexity is judgement, guided by experience and a thorough knowledge of the experimental basis for the model in question. There have been a few papers on the topic of model simplification; you might start by reading this one: Bush, P.C. and Sejn...

Re: Extracellular stimulation
This is the correct approach:
Every segment's membrane should be exposed to its own local extracellular potential.assign e_extracellular values to the center of each compartment?

I don't think I can use the ChannelBuilder because (1) I need to include a Ca2+ accumulation mechanism Apply the principle of modular software design. Specify a Ca accumulation mechanism with NMODL, and specify the channel properties with a ChannelBuilder. (2) my ionic current equation is non-stand...

Intracellular calcium levels were modelled in a sub-membrane shell with buffering and diffusion modelled as an exponential decay. With the equation (that includes the three currents) of the form: [ cai] ' =(Ilca+Inca+Itca)*c*(cai0-[cai])/tca c :is the conversion constant tca:the time constant of th...

first, i inject a current to reach membrane potential to a specific level, and after some delay.e,g 500ms, i use other ICamp current, to study the response of my model. That can work, if the time you wait is long enough (models that have ion accumulation mechanisms--especially calcium diffusion/pum...
