[NEST Users] Re: How does the synapse weight influence 'iaf_psc_alpha' neuron(or any other neuron you know) to send a spike?

Hi Charl, I have a very big problem now again for the iaf neuron(such as iaf_psc_alpha), if I don't know know differential equation for the neuron model, how can I get the derivative about some variable, such as derivative of voltage versus weight. The point is I do need to know the derivative equation of iaf_psc_alpha neuron model to design some algorithm for neural network. For the paper you mentioned, I still can't figure out the exact derivative equation of voltage or voltage state equation. https://link.springer.com/article/10.1007/s004220050570 By the way, At today's meeting, I wanted to ask that but my device had trouble when host asked, haha, so awkward. Hope for your answer or anyone else. Thank you. Enguang
