Hello Anh, We have revised documentation for iaf_psc_exp including equations almost ready. You can preview it at https://nest-simulator--3084.org.readthedocs.build/en/3084/models/iaf_psc_e… I hope it answers your questions. If there should still be something unclear, feel free to comment in the pertaining pull request https://github.com/nest/nest-simulator/pull/3084 Best, Hans Ekkehard -- Prof. Dr. Hans Ekkehard Plesser Department of Data Science Faculty of Science and Technology Norwegian University of Life Sciences PO Box 5003, 1432 Aas, Norway Phone +47 6723 1560 Email hans.ekkehard.plesser@nmbu.no<mailto:hans.ekkehard.plesser@nmbu.no> Home http://arken.nmbu.no/~plesser From: anh.phan(a)tuni.fi &lt;anh.phan(a)tuni.fi&gt; Date: Monday, 1 April 2024 at 13:46 To: users(a)nest-simulator.org &lt;users(a)nest-simulator.org&gt; Subject: [NEST Users] Questions regarding the iaf_psc_exp model [Some people who received this message don't often get email from anh.phan(a)tuni.fi. Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] Hello, I have some questions regarding the iaf_psc_exp model. When it receives current from a current generator (with static synapse), does that current go to receptor_type 0 and not be filtered through an exponential kernel? Secondly, I would like to confirm if the exponential PSCs follow the exponential function:: i_syn(t) = (q / tau_syn) * exp(-t / tau_syn) * Θ(t) , where Θ(t) is the Heaviside step function defined as Θ(t) = 1 fot t >0 and Θ(t) = 0 otherwise. Additionally, is q chosen to be equal to tau_syn? Thank you very much!
