Hi Charl,
Thanks for your reply, that was a mistake on my part..
What I would like to achieve is to access Ca value at neuron as well as synapse level. I tried to look for such example in NESTML but I couldn't find it.
So briefly: 1. How to access superclass variable in neuron NESTML. 2. How to access neuron variables in synapse NESTML file.

Dear Maryada,
Thanks for writing in. Which neuron model are you using? From a simple test scrip with the "iaf_psc_exp" model, I am getting a nonzero calcium concentration:
*import* *nest* n = nest.Create("iaf_psc_exp") nest.Simulate(100) n.get("Ca")
Yields 0.014928834091366892. The "beta_Ca" parameter can be used to tweak the increment upon each postsynaptic spike, and "tau_Ca" is the decay constant.
I am of course happy to work with you to set up a custom NESTML model if you need additional or different features to keep track of calcium concentration.
With kind regards, Charl

Dear NEST Users, I would like to "record" or read calcium concentration of the neurons (let's say aeif_cond_exp). For now Ca variable is 0 before and after I simulate, however the neuron spikes.
Is there any neuron model that supports this, or do I need to edit the nestml of the desired model to achieve this. If so, a sample code snippet would be helpful. -- Thanks and Regards
