no subscripting of SectionList in python

in some cases, the flexibility of python provides some additional functionality that was not available in hoc in current case, I was hoping to avoid prior practice of copying SectionLists onto regular Lists to get random access -- I noted that in Python, a __getitem__ was exposed in dir(h.SectionLis...

Re: mixed model of artificial and conduction-based cells

have you tried connecting 2 of them? -- that would be nice as a demo that this now is useable in the network context
would also be a good thing to add to the modeldb demo

Re: mixed model of artificial and conduction-based cells

yes, this needs to be a POINT_PROCESS which is what it was before

Re: mixed model of artificial and conduction-based cells

as above

you need to use a WATCH statement

looks like you are not doing so

Re: mixed model of artificial and conduction-based cells

Not aware that anyone has done this yet but definitely what i had in mind when i posted the model so i would be happy to help you out with getting this developed and posted. It would appear that the reason i couldn't use a cell V for the 'v' state variable in izhikevich formlation is that the izhike...

Re: _ion_cai ???

This is perhaps entirely historical artifact - I note that the model is that of Desxtexhe 1992. It would be a service if you were able to recast this model into modern form and post the correct current NMODL code here (alerting future users) -- I would also then make the replacement in the ModelDB a...

NEURON distribution license

I was unable to find the license terms under which NEURON is distributed. I was thinking it should be here: http://www.neuron.yale.edu/neuron/about (btw when you search for license or 'public license' etc it returns too much stuff to be useful) This is important since needs to be addressed for Resou...

NEURON+Python hacks

here's a rewrite of forall and forsec in python forall is maybe not very useful since easy enough to just call the hoc version from h() but forsec is useful if you have your sectionlist object-reference in python since otherwise you need to access it via an embedded python interpreter there are also...

Re: Izhikevich neurons and GJs

It would seem fairly easy to copy the voltage over from vv to v -- this would go after the SOLVE in the BREAKPOINT. But this is less than 1/2 the problem since then will also want to get back into vv and this is not a simple copy but needs to add in to the integration. Therefore what you need is the...
