Re: Alpha Synapse with CaDP plasticity

Hi ted, thanks for your support (and Michael Hines support by email). By the secound step that you recomended I can see that when the postsynaptic cell receives an event at time t, the calcium spike will have its peak at t + t1 , where t1 is around 15 ms. That's the problem because all equations ins...

Re: Alpha Synapse with CaDP plasticity

Hi Ted, The model has The USE ca statement and a calcium mechanism. If there is nothing wrong with the NET_RECEIVE block so the problem could be on the palsticity mechanism itself. The only thing strange that I observed is that in some moments eta becomes negative (probably because cai0 is under cai...

Alpha Synapse with CaDP plasticity

Hi, I'm trying to implement in NEURON some calcium dependent plasticity using the alpha function synapse. I know that I need to declare all the equations that control the weight change inside the NET_RECEIVE block but in these case the equations are cai dependent not explicit dependent of time. Ther...
