[NEST Users] Re: Installing an extension module in tvb-nest docker

Dear Nina, If you could provide us with a small, self-contained script that reproduces the issue, that would be great to help with debugging.

I have created my own docker image of the tvb-multiscale but with NEST 3.1 installed. In this container, I can easily install the example nest-extension module, exactly like is explained in the tutorial. Thus, the problem was indeed with the nest version. Thank you all for your answers and help! However, now I have a different problem. So I am now working with (new setup) NEST 3.1 and python 3.9.2 instead of (old setup) NEST 2.18 on Python 3.7.3. I have a simple script to simulate the response of a few unconnected different aeif_cond_alpha_multisynapse neurons to a transient input current. If I run this script in the old setup, it works perfectly and runs in under a second. However, if I run it in the new setup, simulations take forever (I haven't been able to finish one). Does anyone know if this could be attributable to a difference between nest 2 and nest 3 that I haven't incorporated into the script? Should I provide you with the entire script? Thanks in advance!

NMDA receptor conductivity depends on the membrane potential of the post-synaptic neuron (because of the receptor blocking with a magnesium ion). So I would like to multiplicate the NMDA current by a factor which depends on the post-synaptic membrane potential. Is this possible to implement in NEST?

Concerning non-linear NMDA synapses, depending on what kind of non-linearity you want to imlement (just voltage gating or also non-linear interaction between different synapses onto a given neuron), achieving an efficient implementation can be challenging.

Yes I am trying to install the example module exactly as cloned from Github, I haven't altered anything. I think the problem might be indeed as Charl described. But it still could be that it is also a problem that the config.h file is not in the source directory. Thank you very much for the information on the other models! That is very useful! I will definitely take a look at the first model (since parameters are available for different types of thalamic neurons). However, I want to model, besides AMPA and GABA receptors, NMDA receptors. I know modelling actual non-linear NMDA receptors is not possible with the available NEST models. However, what I have done so far with the aeif_cond_beta_multisynapse, is to define different receptors with different time constants corresponding to AMPA, NMDA and GABA post-synaptic potentials. This would not be possible with the NEST models you mention above. However, I will definitely take a look at them and re-evaluate the importance of modelling these different beta-synapse receptors. Thanks again and have a nice day!

So if looks as if something may be off in the pif_psc_alpha.h file around lines 90-92. Are you trying to compile the example module exactly as cloned from Github or have you made any changes to the code? There could also be a small chance of problems "spilling" from the config.h file, which is in the build (not source) directory. That could explain why you experience problems using the docker container, while all works for your colleagues using Linux. BTW, do you know the adaptive multi-timescale models from the Shinomoto group (amat2_exp_psc), which can reproduce the same 20 response patterns as the Izhikevich model, but are mathematically simpler as they are linear?

I am working with the tvb-multiscale docker container ( https://github.com/the-virtual-brain/tvb-multiscale/tree/master/tvb_multisc…) in VScode on windows.

I get a bunch of errors that I have added at the end of this email. My colleague tried to install exactly the same module in exactly the same way on his linux machine and it worked perfectly. But somehow for me, I get these weird errors that I haven't been able to resolve so far. Does anyone have an idea what the problem might be? It would be greatly appreciated.
