Michael, I have a bit of trouble with net_move, specifically when firing rates are high. It can miss events and then stops complitely. I would probably return to cspike counter. It generates lots of events, but somewhat more robust.

I'll try to make an example to show the problem.

This will happen in the master branch of the repository

Should I compile locally? Will it be pushed to pip soon?

What version of NEURON are you using The most fresh from pip. python Python 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> from neuron import h >>> h.nrnversion() 'NEURON ...

It behaves very strange, for example the code below works from numpy import * from neuron import h from matplotlib.pyplot import * wcs = h.WilsonCowanStim() wcs.ratescale = 200 wcs.e_inf = 1.5 rds = h.Random() rds.negexp(1) # set random # generator using negexp(1) - avg interval in NetStim sead = ra...

Thank you, Ted, for your thoughts. The overall bulky construction is because the e-variable of the WC model controls the firing rate of the Poisson generator. Therefore, the rate needs to be updated, and a new time to the next spike needs to be recalculated. If the new time is 'sooner' than the prev...

I need to use the Wilson-Cowan Firing rate model as a counterpart to my multicompartment model. Borrowing some code from NetStim and ignoring that the e and i variables are inside the sigmoid function, I got something like this: NEURON { THREADSAFE ARTIFICIAL_CELL WilsonCowanStim RANGE internal_dt R...

Dear Ted, Thank you so much, for your very helpful comments and suggestions. I saw the problem with the INITIAL block in the CaDynamics_E2 module but somehow ignored it. We need to control cao, because, it seems extracellular calcium concentration drifts during the development period. I implemented ...

I have a model of a V1 pyramidal neuron, with simplified morphology. Somatic, basal and apical compartments have calcium channels and calcium dynamics. Zip archive with all mod files and test-model example can be downloaded here https://storage.r-a-r.org/index.php/s/jLCz6m4k3TXFgmK Only a few channe...

Dear all, My question is somehow related to the Pascal's question https://www.neuron.yale.edu/phpBB/viewtopic.php?f=16&t=4084 because, it seems, I stumbled to a similar problems. I'm trying to play around with Iavarone's model, which uses the same old Destexhe's code https://senselab.med.yale.ed...

Dear NEURON developers, I have run into a very strange NEURON behavior, which I couldn't understand. It relates to the multithreading, but perhaps I did something stupid. I have a simple mod mechanisms UNITS { (mA) = (milliamp) (mV) = (millivolt) (mS) = (millisiemens) } NEURON { SUFFIX nak3dv02 NONS...

ramcdougal, I see your point.

Yes, you are right, it is tricky but may work. Actually very good idea. Of course, it is 'workaround', and it will be better to have a direct way inside NEURON+Python module, but it is nice to have a solution. Let me try :)

Very good point! Thank you!
But how will you use this list to setup point process? Maybe we can use float point position as segment #/nseg ? But this should link somehow to NEURON inner mechanism of position float point resolving.

ramcdougal , thank you, for the suggestion! That is a very neat solution. But if we start from accuracy and electrical length, the number of segments is a constant, unless my dendrites start growing. From this point of view, the best strategy to minimize the amount of computation is to be sure that...

Thank you, Ted, unless they belong to instances of an event-driven point process class (synaptic mechanism) that can be driven by multiple input streams, and you want to exploit that property in order to reduce model complexity and speed up simulations. Which apparently is rth's aim. As you know fro...

Dear All, I apologize for a very trivial question. I have a python class which reconstructs neuron morphology from an SWF file, sets channels and so on. Now with such a nice reconstruction, I need to create 6k - 10k synapses on dendrite tree. Moreover, there are about 5 different synapses classes, w...
