I can use NetCon.active(0) to turn the NetStim events off at&after detected time point. Alternatively, by setting NetCon.weight=0 works similarly. You should probably run a test to make sure that whatever you're doing is working properly. Executing netcon.weight[0] = 0 at some time t should prevent...

Good question. See I just want a current clamp that will deliver a sequence of current pulses at regular intervals. in the FAQ list https://neuron.yale.edu/neuron/faq/general-questions This is also mentioned in the Hot tips area of the forum under How to make IClamp deliver multiple pulses or a wave...

Not flag. weight. weight is an attribute of a NetCon. Quoting directly from the documentation of NetStim: If, in the on=1 state, the stimulator receives a negative weight event, the stimulator will change to the off state. But to do that, you'd have to create a special NetCon, with negative weight, ...

I already implemented real-time detection part Good. That's the hard part. When the condition "time to turn off the NetStim" happens, use a NetCon's event() method to send an event with weight < 0 to the NetStim that you want to turn off. Read the Programmer's Reference documentation of the NetStim...

It should be possible to use NEURON's Import3d tool to convert the swc file to a hoc file. Adding an axon and assigning biophysical properties will be easy. Easier yet would be to have the Import3d tool export to a CellBuilder, then use the CellBuilder to set up Subsets, spatial discretization, and ...

It will be interesting to know if the translated version of the model produces results identical to the original, and if not, what fixes are necessary to resolve the problem.

trying to modify morphology of detailed models Read about 3d specification of model geometry. In fact, read everything on this page https://www.neuron.yale.edu/neuron/static/py_doc/modelspec/programmatic/topology/geometry.html or the corresponding page for hoc https://www.neuron.yale.edu/neuron/sta...

Answered on the FAQ ("frequently asked questions") page of the NEURON Forum https://neuron.yale.edu/neuron/faq/general-questions -- see I installed a new version of NEURON, and now I see error messages . . . While you're there, you might find it useful to look at some of the other questions and answ...

Good guess, but do this instead: If you plan on using NEURON's GUI tools, do this If you intend to take advantage of its standard run time library

The link you provide is not to the file that implements the Na-Ca exchange mechanism--instead, it produces a list of ModelDB models "that contain the Current : Na/Ca exchanger". None of them happens to be by Courtemanche et al., which is very strange indeed, since the very paper by Courtemanche et a...

The example is in hoc, but it's easy to implement the same approach with Python.

I seem to be still getting minor variations in voltage in some cases. Looks like I'll have to be able to reproduce this in order to figure out what's going on. Can you zip up the necessary code and email it to ted dot carnevale at yale dot edu? and also include instructions for how to reproduce wha...

Did you ever use SaveState before, to do anything? Build a toy model and try it out with that toy model. When you get that right, try something more complicated.

Important facts 1. The NEURON simulator can be used to execute programs written in hoc, or Python, or programs that contain hoc and Python statements. 2. Because of fact 1, there are two versions of NEURON's online Programmers' Reference. One focuses on how to use NEURON with Python, and the other ...

Thank you for your interest. On Friday, Oct. 17, 2019 there will be a 1 day course on NEURON at the Society for Neuroscience Meeting in Chicago.
