Why does same model produce different results on PC and MAC?

Hi everyone I developed thalamocortical model on MAC book pro with NEURON version 8.1. I ran same model on Windows operating system with NEURON version 8.0 but I found significant difference in both PC and MAC book results. Can somebody help me how can I fix this problem to get same/correct results ...

Re: How to change runtime synaptic conductance?

I have implemented FInitializeHandler. But I am still facing same problem. I noticed this error during simulation. exp(702.716) out of range, returning exp(700) exp(702.469) out of range, returning exp(700) exp(702.64) out of range, returning exp(700) exp(705.532) out of range, returning exp(700) I ...

Re: How to change runtime synaptic conductance?

Dear Sir Again thank you very much for your reply and help! You asked about " what is your definition of "the start of a slow oscillation cycle"? I am using second strategy. Once a spike is detected, t_change flag (initially t_change = 0 (synaptic weights will zero or very low)) value...

Re: How to change runtime synaptic conductance?

Dear sir Thank you very much for your kind reply. I implemented FinitializeHandler() in my code and it works. In my case I need to apply synaptic delay for each up state of slow oscillation cycle. For example when I start simulation the first slow oscillation cycle will also starts and I want to to ...

How to change runtime synaptic conductance?

I am working on thalamocortical model for slow oscillations. Actually, I want to change thalamic synaptic conductance during each slow oscillation cycle. For example, when slow oscillation cycle will start, during initial 500 ms, I want to block synaptic conductance between thalamic and cortical net...

Re: How to activate network by synaptic mini current after time 50 ms when all network cells get silent

I tried to used this artificial cell autogoad in my model. I am facing one problem. autogoad cell can not receive input from network cells i.e. PY cells. I think, that there is connection issue from PY cells to autogoad cell. How can I connect multiple PY to single autogoad cell PY-->autogoad (Multi...

Re: How to activate network by synaptic mini current after time 50 ms when all network cells get silent

Dear sir Thank you very much for your kind reply. I think I did same as you mentioned. Every cell in your network will project to the artificial spiking cell via a NetCon; proc net_stim() { local i localobj ns, rs, es, is, r nslist = new List() rslist = new List() eslist = new List() islist = new Li...

Re: How to activate network by synaptic mini current after time 50 ms when all network cells get silent

Yes sir I mean this "when no cell has fired a spike for at least N milliseconds." That's easy to implement. If that's a good enough definition for your purposes, fine--decide what is an appropriate value of N." For instance last spike was generated by any network cell at 500 ms, I wan...

How to activate network by synaptic mini current after time 50 ms when all network cells get silent

Hi everyone I am developing thalamocortical model for slow sleep. I am facing some issues in network stimulation and need your help. 1. For network activation I want to give a synaptic mini current. 2. After this stimulation, as network cells start firing mini current should be stop. The network cel...

How to implement short-term depression in cortical area?

Hi all I am constructing thalamo-cortical network for slow oscillations. The AMPA and GABAa currents are given by Isyn = gsyn[O](V-Esyn) in TC cells to PY cells and PY to TC and RE cells. But I need to add synaptic depression by term D in intra cortical network modifying synaptic current by Isyn = D...

.mod files compilation issues

Hello I faced a problem in NEURON project compilation on LINUX Ubuntu. I installed NEURON on home directory. When I compile project’s mod files, the system generates x86_64 folder in home directory instead of project folder. When I compile mod files of other project, new .c and .lo files are generat...
