A very simple Voltage-clamp experiment

Dear forum members, I am trying to study the effect of the series resistance on time course of synaptic currents. For that, I first created a very simplified model of a soma and an "alpha synapse" attached to it . To perform the measurements, I would like to voltage-clamp the soma at -70mV and get t...

Re: UNITSON and UNITSOFF to remove inconsistency?

I totally agree with you, Exp2Syn is what I needed. In any case, I wanted to get familiar with NMODL language, and this was a very good opportunity.

Thanks a lot for your patient and care!

Best.

Re: UNITSON and UNITSOFF to remove inconsistency?

Thanks a lot for your fantastic advices! This is my first mod and It would have took me ages to get to that! Now I am ready to start the simulations. The real mechanism would look like this (just if somebody wants to use it): :synapse.mod TITLE Synaptic conductances of CA3 neurons COMMENT synaptic c...

UNITSON and UNITSOFF to remove inconsistency?

Hi everybody, I am just adding a new mechanism to model a synapse by the product of 2 exponential functions, as follows (very simplified): NEURON { POINT_PROCESS syn RANGE gmax, tau0, tau1, e_rev, i NONSPECIFIC_CURRENT i } UNITS { (nA) = (nanoamp) (mV) = (millivolt) (uS) = (micromho) } PARAMETER { t...

Dear Ted, thank you very much for your wisdom advices (and specially for the model-specific comments). The problem was solved changing just the temperature (and I changed V_init as well). I've just started with Neuron, and I need to become more familiar with it (I own the book, by the way). Actually...

single spiking soma.

Hi everybody, I am just staring with Neuron. I tried to create a soma with hh conductances. When I insert everything in the console, the model runs properly (i.e. I see the action potentials). However, when I load directly the .hoc file, I only see an step in voltage in response to a current step. /...

To compile you need not only the compiler, but also the corresponding libraries. I would try to install the following libraries (in bold the debian name package). For gcc libc6 - GNU C Library: Shared libraries libc6-dev - GNU C Library: Development Libraries and Header Files checking for tgetent in...

I changed the location, so it's easier to find:
Here the Neuron 5.9 in .deb format ( 4.2 MB)

http://neurohost.org/index.php/Downloads

I hope it works!

Regards!

So, it's not that important for working with Neuron at this moment!

Thank you very for your help. Nice FAQ by the way.

Problem with JAVA

First of all, let me introduce myself. I am an experimentalist just starting with Neuron (fantastic feature!), and this is my first post here. After installing the last version of Neuron in my Debian machine, and running nrngui, I found the following problem: NEURON -- Release 5.9.10 (1601) 2006-11-...

I wanted to use the last version of Neuron in Debian, so I transformed the *rpm package into a *deb, and it worked fine for me.

You can find the deb version in my website to download, just here:
