I know I can find the transfer impedance for a pure frequency What constitutes an impure frequency? What to do depends on whether you prefer to operate in the frequency domain or in the time domain. If you want to operate in the frequency domain, then for any pair of locations of interest you'll ha...

Comments: 1. Iteration over all sections is required because ena is a range variable, not a global variable. 2. Iteration over all segments is not required because the syntax sectionname.rangevarname = somevalue assigns the value "somevalue" to the range variable in all segments of the ref...

It's pretty straightforward in Python too. Try to think about the problem as being "how to iterate over all sections." This is easiest with the idiom for sec in h.allsec(): one_or_more_statements Example: suppose you have just created a bunch of sections and you need to insert hh into all ...

Thanks for following up on that.

What "myelin double circuit model" are you referring to? With regard to models of spike propagation in myelinated axons, many authors have published such models. Most of them use very simple representations of the electrical effects of the myelin sheath. Whether one is better than another ...

Those files are from an exercise that was part of the 2018 NEURON Summer Course. Download and expand this file

The programs initbatser.py and initplotfi.py both need to use a procedure called plotfi, but plotfi is not built into Python. Instead, it is a user-written procedure that is defined in plotfi.py, which is in the same directory as initbatser.py and initplotfi.py. The statement from plotfi import plot...

There's a lot of "stuff" (code complexity) in that implementation of the Izhikevich model. It would be easier to incorporate simple representations of excitatory and inhibitory synaptic transmission, similar to ExpSyn and/or Exp2Syn, into your January 26 twocomps model. ExpSyn-like excitat...

It will be released when it's ready.

Sorry about that. The site's architecture has changed several times over the years, and some old URLs were not updated. The updated link is https://neuron.yale.edu/neuron/static/p ... p2.htm#3.2

Thanks for that information.

I would also expect that nrnivmodl (or mknrndll) would generate an error message if it encountered duplicate SUFFIXes when compiling mod files.

In my case, the source of the error was a naming conflict between mod files, where they shared the same user defined name.

Do you mean to say that the mod files had the same name? Or that their NEURON blocks contained identical
SUFFIX
or
POINT_PROCESS
or
ARTIFICIAL_CELL
statements?

Thanks, but I'm just standing on the shoulders of giants. More credit goes to those who are responsible for the hard work of software development (not to mention getting support for such development). The list at http://neuron.yale.edu/neuron/credits lags behind the growth of the development team.

It's always good to use meaningful names so a program automatically documents itself. One more hint: you can verify the existence or nonexistence of objects by using h.allobjects("classname") to discover the names of all instances of the named class (as well as the reference count for each...

Very good question. The answer is yes, but "yes" doesn't tell you how to do it, or what complications might arise. For example, did you know that, by default, there is only a single pseudorandom number generator, and that everything that needs a "random" number will get its numbe...
