Re: How to save synaptic changes?

Thank you for your detailed explanations. I built a toy model. There is a little difference between what is expected and what the results from STDPE2.g show. Firstly, [“Set the NetStim to generate a single event at 1 ms, and set the NetCon's delay to 1 ms and its weight to 0.001. Run a simulation an...

Re: How to save synaptic changes?

I tried to work with potentiation degree but, it is not good enough for my purpose. I really need to find out conductance. When I save “ncslist.o(i).weight[0]”, this generates the same initial conductances that was set in “connectCA3”. It seems that “ncslist.o(i).weight[0]” cannot track conductances...

Re: How to save synaptic changes?

Thank you for your reply. Your previous comments were very helpful. I still have some problems! As I have mentioned, I need to specify potentiation degree of each synapse in a network of 100 CA3 cells, each of which connecting to 100 CA1 cells. There is a procedure named “connect CA3” that connects ...

Re: How to save synaptic changes?

Thank you for the explanation. I use this model: http://senselab.med.yale.edu/modeldb/ShowModel.asp?model=123815 And here is the NMODL code for implementing STDP: : STDP by Hines, changed to dual exponential (BPG 6-1-09) : Modified by BPG 13-12-08 : Limited weights: max weight is wmax and min weight...

How to save synaptic changes?

Hello, I use a network similar to network of Cutsuridis et al in his paper ‘’Encoding and retrieval in a model of the hippocampal CA1 microcircuit’’ . There are 100 CA1 pyramidal cells in this network, each of which receives input from 100 CA3 cells. Synaptic weights are modifiable through STDP lear...
