Re: Help varying membrane voltage fluxuation

First, thank you for your search for the figure. I apologize for providing an incorrect reference. After weeks of trying and reading, I have finally fluctuated the SD of the membrane voltage by reduce the total number of excitatory and inhibitory synapses (~900/300). In my original code, I used a se...

Help varying membrane voltage fluxuation

I am trying to reproduce some of the results of Alain Destexhe in his paper "High-Conductance State of Neocortical Neurons In Vivo (image below), in particular Fig. C1)." If I am trying to vary the membrane voltage fluctuation (SD = ~4 mV) of my system, what parameters would I theoreticall...

Re: Adding Synapses to Pre-existing model

Thanks for all of the clarification of the initialization, spacial discretion, and checking the morphological data! I understand better now and have made the appropriate changes. In particular, you explanation for the NetCon list makes a lot of sense. I was dumb to assume that NEURON would just keep...

Re: Adding Synapses to Pre-existing model

Sorry, but another quick question... I would like the excitatory synapses to have excitatory quantal conductances of 1 nS. Is there a parameter I could easily change in Exp2Syn to achieve this? I thought about changing the synaptic current (syn.i) to 1 nA, but I know this is insufficient in changing...

Re: Adding Synapses to Pre-existing model

Thanks for the great insight Ted. For the initialization I think I will try to use GUI's VariableStepControl tool to initialize the model to steady state at the beginning! I have been reading up on the GUI and I believe by loading the parameters the GUI outputs from the ses file, it should be suffic...

Re: Adding Synapses to Pre-existing model

Dear Ted, thank you for your quick and detailed response! It has been very helpful into guiding me in the right direction. It is unfortunate that modelDB is not working, so would you like me to send you the zip file that contains my code as well as the original code for the modelDB file I am using? ...

Adding Synapses to Pre-existing model

Dear Ted, Thank you for all of our previous interactions. II have been working with NEURON for the past couple of weeks and I fainlly feel I am now somewhat competent after reading and testing my understanding of what NEURON can do. My current goal is to successfully add X number of excitatory synap...

Re: Adding Synapses (Excitatory and Inhibatory) - Staring He

Thanks for your suggestion Ted! I have been reading and using the AlphaSynapse built in function in NEURON and was wondering a question. Can you put multiple AlphaSynapses in a cell model and have then both fire at different times? I have used a simple model with soma, dend[2], and an axon. I placed...

Adding Synapses (Excitatory and Inhibatory) - Staring Help

Hey guys, I'm trying to understand how to add excitatory and inhibitory synapses to a simple cell and have been reading a lot of things online. I'm not really sure where to start, and I was wondering if anyone could point me in the right direction? I know in order to add these synapses, you have to ...

Re: Implementing a CHIRP stim and recording the soma

Thanks so much Ted! I've read both links as well as messed with more NUERON coding, testing my understanding of how the language works. In regards to the second link you provided, I had a question about the outline of a program you were discussing. Corinne tried to write "a program that determi...

Implementing a CHIRP stim and recording the soma

Hello all, My ultimate first goal is to implement a CHIRP stimulus into this model (https://senselab.med.yale.edu/modeldb/showModel.cshtml?model=139653) at various points and record the neuron at different points. This information will be then used to find the resonance of this model. I have been wo...
