Hello Charl and Beck,

I would be interested to join the discussion, as I am currently trying to implement gap junctions too in an AdEx model with NESTML. Since maybe I'm not the only one interested, could you post the meeting time and the zoom details?

Best regards,
Razvan

Hi Charl,
Yes, I would greatly appreciate a deeper dive into this with you. Can you write to me directly at bstrohmer@gmail.com so we can find a suitable time? Thanks so much! 

Best,
Beck

Hi, thanks very much for your inquiry!

To add a gap junction to a NESTML model, a few modifications to the toolchain would be required. A first idea would be to add a new input port with a type of "gap". If a gap junction port is present, we could then generate the handler for a GapJunctionEvent, as well as to generate the necessary code for the waveform relaxation mechanism in the update() method of the neuron.

If you'd like to do a deeper dive into this together, I would be happy to have a video call this week or the next (after that I will be in Marseille for the HBP Summit). Please let me know what options would work best for you.

Yours,
Charl
