Hello to all, I am trying to modify the file nmda2.mod file from http://senselab.med.yale.edu/ModelDB/Sh ... 3808&file=\MyFirstNEURON\nmda2.mod so that it writes the calcium current, ica, and that it responds to an event received by a NetStim. I get the error NMDA_S cannot be used with CVODE I t...

Thank you.

Hello to all,

what is the argument to the function set_seed() used in pregen.mod, for example? Does it need to be an integer (I don't know about random number generators)? It works with passing a floating point number to it, but is it maybe truncated?

Best regards

Hello to all,

which pow function does this refer to? Is it the exponentiation function exp used in the end of the mod file?

Best regards

Very well. Before doing it, I will mention what I have tried doing. A neuron with many excitatory synapses receiving Poisson input trains. The interval for a NetStim, representing the Poisson train is set as the inverse of a rate, and the number of spikes as (rate * stimtime), where stimtime is the ...

Hello to all, I don't understand what the field 'number' in NetStim is. http://www.neuron.yale.edu/neuron/static/new_doc/modelspec/programmatic/mechanisms/mech.html?highlight=netstim#NetStim Does it refer to the (average) number of events to be generated during the whole period where NetStim is to b...

I see. Very well, thank you!

Hello ted, it was/is helpful, because knowing that I continued searching where the error is. Thank you. I have another question on the same topic: is the part if (cvode.active()) { cvode.re_init() } else { fcurrent() } necessary for this example (changing the weights of NetCons)? The results look th...

Hello to all, i would like to change the weight of a NetCon (i.e. many NetCon objects) at a point during the simulation. Would sending an event via cvode.event() be the way to do it? I have tried it, without success, and am wondering if I am not doing it properly or if it is not the way to go. Best ...

Very well. Thank you very much!

Hello,

I have encountered the same problem on Scinetific Linux 6. The version of NEURON is 7.1. I cannot run neurondemo as a root user, the machine is administered by the local IT Systems group. Do you have any suggestions as to what to do?

Best regards.
