Dear Jan,
Thanks a lot for your explanations!
I will give it a try, starting from the dev workflow (https://nest.github.io/nest-simulator/development_workflow), and maybe come back at you / nest users in case of problems... :)

Dear Domenico,
it is true, that at the moment 'hh_psc_alpha_gap' and the most recently added 'hh_cond_beta_gap_traub' are the only predefined model that supports gap junctions. However, in general it is possible to add gap-junction support to almost any model in NEST by adding the necessary support for GapJunctionEvents to the C++ code of the neuron model.
If you are interested in creating a new model with gap-junction support: The best way to do so is to start with a copy of an already existing AdEx model and then add
* the I_gap term to the differential equation of the membrane potential (see hh_psc_alpha_gap, lines 129-152) * the computation of the membrane potential interpolation (see hh_psc_alpha_gap, lines 610-639) * the corresponding handle function "handle( GapJunctionEvent& e )" (see hh_psc_alpha_gap, lines 711-725)
and the required buffers and adjustments for the iterative solution scheme. Comparing the model code of 'hh_psc_alpha' and 'hh_psc_alpha_gap' gives you a good overview of everything that is needed. If you need any assistance in the progress you can also contact me any time.
Please also note: For the future it is planned to integrate gap-junction support in the modeling language NESTML, which will enable you to create new models with gap junctions without actually touching the C++ code. However, there is not yet a fixed timetable for when this will be available.

Hello,
from the NEST docs(https://www.nest-simulator.org/simulations-with-gap-junctions/), I see that only the cell model 'hh_psc_alpha_gap' can use gap junctions. Is it true? If true, are there any plans (or hacks) to have it also for the AdEx model?
