Hi!! I load the value located in the file with success. But i can't affect this value to the electrode. There is a syntax error according the simulator. This is a part of my program, if you want, i can send you my project. //recuperation.ses objref minfvec, vvec amp_electrode = 0 minfvec = new Vecto...

I made one program, but it didn't work //begin.hoc load_file("nrngui.hoc") load_file("window_value.ses") //window_value.ses proc load() {xopen("loading.ses")} { xpanel("Loaded Value", 0) xbutton("Load","load()") xpanel(500,600) } //loading....

Load a value located in a text file

Hi !!
I try to load in one electrode an amplitude which is written in a text file with NEURON.
How can i make it?

Conduction velocity

Hi
I try to calculate the conduction velocity after a simulation run.
Can you help me in this realisation?

Yes, it works.
But now, i try to stimulate a zone of my model with the help of the point process window.
How can i select a zone or more than one point with it?

Stimulation on a zone

Hi
In my model, I have 20 nodes and I want to stimulate 3 nodes, chosen by the user, at the same time and to draw the answer on a graph.
How can i make it?

No, i didn't yet read this book. But can you explain me, the spatial discretization.

New model

Hi!!
I try to make my new model. But i don't know, how to associate the node number, the node diameter or the node length in NEURON.
Someone know, if this parameters can be integrated in NEURON.

In your code, you use

Code: Select all

soma ocbox_ = new PointProcessManager(0)
And in the point process window there is a soma.
Does your model have a soma?
No, there is no soma.
I try to simulate on the fibers or the dendrites.

An aside: I just noticed something very strange. Apparently, when I replied to freddy09's question, I hit the "edit" button instead of the "quote" button. Then, without noticing my error, I destroyed much of what freddy09 had written. Finally, when I "submitted" my rep...

Step 3 undoes everything that X did in step 2. For my project, at the beginning the CellBuilder helped me to create a model with some dendrite and axone. But later, the CellBuilder will not make modification on the model. And the X user should not have access to the CellBuilder. please tell me some...

What kind of a stimulus are you using--an IClamp? I use an IClamp for stimulus. Do you mean to say that increasing the diameter causes a reduction of the effect of the IClamp's current on membrane potential? Yes, if i increase fiber's diameter, i decrease the effect of the stimulus. And for the usi...

another question

Hi Ted!
I believed that the loop's goal was to associate some parameters to the dendrite, for the use and the modeling in the CellBuilder.
So could you tell me, how to change dendrite's parameters, like number of segment or fiber's diameter in the extracellular stim ?

Thanks!
