Re: Way to change properties of a section's individual segme

Dear Ted, I think I understand better now your first response too. Thank you very much a lot for elaborating and thank you for proposing another way too, it's really helpful! For affirming this answer: Was that result unexpected? The section's first two internal nodes are at 0.045... and 0.136..., s...

Re: Way to change properties of a section's individual segme

Dear Ted, Thank you very much for your answer. From what I understand, it is impossible to achieve the correct spatial accuracy with rangevar and nseg in order to manage having specific parts/segments of one single section with distinct parameter-biophysics' properties. It is a bit strange though ho...

Way to change properties of a section's individual segment

Dear all, I think I found a way to change the properties of the different segments inside one section, however I am not sure whether indeed this is correct . I will give below an example and I would really appreciate it if someone could tell me if indeed this does what I am aiming for (changing prop...

Re: Multiple Strings' Names production

Dear Ted,
Thank you for your reply! I was using this command for generating different-file names and did not see it used also for creating different strdef names. Very helpful!
Thanks again!

Best,

Multiple Strings' Names production

Dear all, SITUATION: I would like to store in one single file several data that I am obtaining from my .hoc model (a myelinated neuron-cell). And for this I need to have the titles of the data-to-be-stored in the first line of my file. However, since it is a myelinated cell, the number of myelin com...

Re: Neurolucida to NEURON diameter missing problem (swc file

Dear Ted, Thank you again for your invaluable help! I am writing here to give the correct way I think I found of transforming a Neurolucida .dat file to a .hoc file for everyone to check if they (may) encounter problems too. The main key-problem as you told me at an email is that: In the swc file th...

Neurolucida to NEURON diameter missing problem (swc file)

Dear all, I am trying to import a morphology from Neurolucida (generating a swc file from a Nurolucida-dat file) to NEURON. The file is properly loaded to the Cell Builder of NEURON and then I export it to a hoc file. However with one psection() I see that the diameter information is not there and g...

SectionLists() import at the CellBuilder - Problem

Dear all, I am creating in a hoc file a certain cell (created with all proc: topology, geometry, biophys, etc) but when I import it into the CellBuilder some of the cell's features are not imported: i.e. the SectionLists() I made for each section are not there; the diam, length, nseg characteristics...

Re: Conduction Velocity & spikes' characteristics recording

Dear Ted, Thank you very much for your quick reply, it is really helpful! I will try as you suggested and will test a few things out. To answer your question, yes, there is an axon. The topology consists of a soma, an Axon Initial Segment (AIS) and an axon with some myelin. The CV measurement I was ...

Rm alteration for myelin modeling

Dear all, I was wondering: how can one incorporate the membrane resistance (Rm, [ohm-cm^2]) of a section into Neuron? I am modeling myelin, and the Rm and Cm (membrane capacitance) are both changing in the myelinated sections, from the values of the non-myelinated axon. However, nowhere in Neuron is...
