Dear All, a (very) long time ago, I used the "Linear Circuit Builder" for simulating a (fancy) extracellular electrode ( https://senselab.med.yale.edu/ModelDB/showmodel.cshtml?model=112086&file=/giuglianoEtAl2007/readme.html ). Today, I would love to expand on that idea and make a more...

Same problem, under macOs (python 3.9.10) using NEURON 8.0.0 HEAD (429d11ef) 2021-04-30 :-(

I also get the same under Linux (python 3.9.7, same NEURON version).

Thank you for your precious answer.

I am preparing a simple PYTHON-NEURON tutorial and found I am unable to use finitialize() properly. In the minimal code, below, the initial condition set by finitialize(-100) is ignored and the simulated voltage trace starts at -65mV. Why? Can anybody help me, understanding where is my mistake? Than...

Yes, it would be a terrific idea and similarly it would be nice to have the graphs appear inline.

Dear All, I implemented the channelrhodopsin model ChR2 (H134R mutant), described in a recent PLoS Comp Biology paper[1], as a nonspecific current mechanism. I have then shared this model on ModelDB (accession number 244414; to become public in the coming days). Given my limited proficiency in NEURO...

Posting in a prestigious forum as this one has strange (positive) effects: debugging occurs telepathically ;-)))))) I have now solved my (presumed) numerical instability upon removing one of the o.d.e. describing the kinetic scheme: they are NOT all independent and NEURON probably was annoyed by my ...

Presumably this would be a re-implementation with NEURON of a previously published model. Several such models have been published--which one do you have in mind? Are you familiar with Williams JC, Xu J, Lu Z, Klimas A, Chen X, Ambrosi CM, Cohen IS, and Entcheva E Computational Optogenetics: Empiric...

I need to implement and simulate a network of multi-compartmental neurons, "sitting" on a conductive film (e.g. a giant substrate metallic/non-metallic microelectrode). Mathematically I know I need to solve a 2D Poisson equation, specifying ad-hoc current sources and sinks (not uniformly d...
