Ted, Yes, you are right, this is an *approximation* and not a bug. You might want to change the wording on the webpage to state that. Your suggestions are helpful. I'll simulate some synapses explicitly to make sure the concentrations do not affect the membrane properties. Thanks for the prompt repl...

membrane mechanisms 'bug'?

Hello again Ted & Michael, Rather than starting a new thread, this one seemed a reasonable place to ask this question. As stated in the discussion above, NEURON is able to include the contributions of both active membrane channels and synaptic conductances into an impedance calculation. However,...

IV-17 on RedHat Enterprise 4 (64 bit)

I want to compile Neuron-6.1 on a 64 bit machine running RedHat Enterprise Linux Version 4, but have first come across an error when compiling iv-17. The ./configure step finished OK, but the 'make' command exited in src/lib when trying to build 'libIVhines.la'. This error seems to be the culprit: l...

Thanks Michael, that did it!

I didn't realize that a new version of InterViews had been released since the last time I downloaded it.

Now I'll try my hand at the new and improved NEURON!

Compiling Neuron 6.0 on Unix (Mac cluster)

Hi Ted and Michael, I am eager to try out the new version of Neuron, but get an error when compiling it myself. We have a cluster of Mac G5 processors running OSX; I've always used your Unix/Linux compilation instructions to compile Neuron there with no trouble. I put the IV & NRN tar files into...

Thanks Ted. All three of these references look interesting and certainly relevant. Particularly the Colbert and Pan paper demonstrating that the kinetics, not the densities, of axonal channels may be critical to AP initiation and propagation. The proximal region of the axons were reconstructed in th...

Modeling the axon: how much detail?

To Ted, Michael and the NEURON Forum: I am developing a model of a neuron (from the goldfish hindbrain) using detailed 3D soma and dendrite morphology reconstructed with Neurolucida. We are studying how dendritic morphology and active channels contribute to somatic firing patterns. Before incorporat...

Some success, but still some errors.

Michael, Thanks for your suggestions and your quick reply. I'll keep mode files + VERBATIM in mind when looking to use C functions. And looking at atan2() in math.c was indeed helpful; that's how I got my function running in the first place. When I emailed yesterday, I had been running a variant of ...

Calling C functions from NEURON

Hi all, In general, I have a few questions about calling C functions from within NEURON. Specifically, I am looking for a NEURON function that takes a floating point number, and returns the 32-bit representation (sign bit + exponent + mantissa; 64 bits for doubles) of that number in the computer. In...
