Applying a low frequency

[mkr35]

Hi everyone,

I am currently working on a project where I need to apply a low frequency to an epileptic pyramidal cell. However, I am unsure of how to do this. I was thinking of creating an iclamp and stimulating that way with a a sinusoidal function. However, I am not entirely sure as to how to do this, due to the fact that I am still very new to neuron. Any feedback would be great.

Thank you for your time.

First get NEURON running properly on your machine. Then search the Forum for Izap.

Okay I found the file, but I'm not sure how to change it to what I would need it to do. Since I need to apply it to a pyramidal cell and apply the low frequency I am also not sure how to change the frequency. Is there any file that explains how the izap.hoc file works? Thank you for your time.

You don't change it. You use it as is. If necessary, change its parameters either by assignment statements in hoc or Python, or by using a GUI tool like the PointProcessManager.

I am also not sure how to change the frequency.

Read izap.mod's header to discover Izap's parameters. In the PointProcessManager click on Show/Parameters, and use that tool to change the parameters.

From where are you getting your model cell? Do you have a hoc file that specifies its anatomical and biophysical properties, or what?
