Re: Single, myelinated axon with several nodes and internodes
MechanismStandard was designed as a tool to use for building other tools--specifically, for constructing graphical user interfaces such as the Cell Builder. As such, it has certain properties that are particularly useful in that context (i.e. machine-generated code that is written to ses files), bu...

Re: Single, myelinated axon with several nodes and internodes
I used the GUI interface to build my model so I assumed it's the default; why might that be a problem?ted wrote:Are you following an example obtained from ModelDB, or somewhere else, or is there some other reason for using MechanismStandard?

Re: Single, myelinated axon with several nodes and internodes
Your clue will be in the hoc statement that changes the params of axon1[9]. Below is what I think is the relevant code, but I don't see the problem: tobj = new CellBuildSection("axon1",9, 0, tobj, 1) slist.append(tobj) tobj.parent=slist.object(10) { tobj = new MechanismStandard("pas&...

Re: Single, myelinated axon with several nodes and internodes
I'm still working on this model. I currently have the following topology: lead-node1-axon1-axon1[1]-axon1[2]-axon1[3]-axon1[4]-axon1[5]-axon1[6]-axon1[7]-axon1[8]-axon1[9]-node2-axon2. node1 and node2 are HH nodes that are 10 micrometers in length with everything else being passive. Each axon1 secti...

Re: Model axon
Thanks! Doing it one pulse at a time let me fix the problems.
Do you have any recommended capacitance and conductance values for myelinated axons?

Model axon
I have a question about a model I'm building. My model is an 1000 micron axon followed by a 10 micron node; the axon has passive cable properties while the node has HH properties, but it doesn't appear that the node is firing regardless of what current I put in (using the ipulse1 PointProcess). Here...

Re: Single, myelinated axon with several nodes and internodes
Thanks. I tried to load the models in brill77 and received the following error: nrniv: hoc_sf_ not declared at the top level in pointman.hoc near line 30 external hoc_sf_ ^ xopen("pointman.hoc" ) execute1("{xopen("pointman.hoc")}" ) load_file("pointman.hoc" ) ...

Re: Single, myelinated axon with several nodes and internodes
Thanks. Right now, I'm looking for something extremely simple for me to compare my basic models with. I'd like a to find a single axon with passive internodes and HH nodes that fire if the voltage change is high enough. I'd like to tackle additional biological complexity later, but for now, simple i...

Single, myelinated axon with several nodes and internodes
Is there a good example of a myelinated axon model that's available for me to work through?
Thanks,

Re: Compiling Ipulse1
Thanks! I put the pulses in the folder with my SES files, compiled them, and they load when the SES file is opened.

Compiling Ipulse1
Hi everyone, I'm using Neuron 7.1 on my Windows computer. I'm trying to install Ipulse1 & Ipulse2, the regular pulsing MOD files that can be downloaded from the Neuron website, but must be doing something wrong. The files are currently stored in C:\nrn71\bin\pulsedistrib and I have the compiler ...
