Re: Tsodyks-Markram synapse model
Hi, I tried figuring out why exactly gmax is assigned to 0.001 uS (1 nS) in the implementation of the Tsodyks-Markram model (code pasted above this post), but to no avail. My question is, why use a gmax value of 0.001 uS, and why not any other value? I tried running simulations with various gmax val...

Re: Tsodyks-Markram synapse model
Thanks again Ted... below is the whole code... I changed g=gmax*(B-A) to be part of the BREAKPOINT point from what you pointed out. I looked at the implementation of this synapse model in ModelDB, which does contain a gmax value, and also does not use variables A and B, but uses a 'term' state_disco...

Re: Tsodyks-Markram synapse model
Thanks Ted... I have another question... why is it necessary to have a gmax value in the parameter block in a synapse model? Is it a scalar value that scales the time varying conductance g, given by g = gmax*(B-A), where A and B are variables that vary with the NETCON weight? I have a chunk of code ...

Tsodyks-Markram synapse model
The implementation of the Tsodyks-Markram synapse model in ModelDB does not have g set to any initial value... The reference Tsodyks et al., based on which the model is created does not mention any g value... Could g be assumed to be the gmax value for AMPA synapses, which lies in the range 1 - 2.7 ...

STDP using FOR_NETCONS
Hi I'm looking at incorporating STDP in a model of the neocortical column, and came across Michael Hines's code for the same. I'm rather curious to know what the FOR_NETCONS keyword does precisely. However, I could not find any documentation explaining the same in greater detail. Another thing that ...

dropdown menu
'm trying to build a GUI for synaptic diagnostics. Basically, what I'm trying to do is to have a GUI with the following parameters: 1. NetworkPath (displays the network path for my simulation) 2. Total no. of neurons (displays the total no. of neurons in my network) 3. MorphPath (displays the morpho...
