Re: AMR for increasing computation speed

Thanks for the reference! So basically they didn't update branches of the neuron that were at steady state, but updating an entire branch if it was not at steady state. I found their followup paper where they did some simulations. Rempe MJ, Spruston N, Kath WL, Chopp DL. Compartmental Neural Simulat...

AMR for increasing computation speed

Has anyone ever heard of a neuron simulator using adaptive mesh refinement (AMR) for the cables? I'm looking for a little research project to do and this came to mind. A cursory look through available software and research papers had no results for AMR applied to the Cable equation. Does anyone know...

Re: Typical number of compartments for neuron discretization

That's exactly what I needed to know. Some sort of estimate for good upper and lower bounds.

Thank you much,

Typical number of compartments for neuron discretization?

I was able to find many posts on how to pick a good number of segments with the d_lambda rule, and also symptoms of the discretization being too coarse for the model parameters, but what I really want to know is what is the typical number of compartments necessary to model a typical neuron. I don't ...

Re: Maintaining Second Order Accuracy at Branch Points

To answer your second question, the equation is (2) in "Efficient Computation of Branched Nerve Equations"(Hines 1984). Also, I've changed the date to 1984, as that is the correct date, not 1983. http://www.neuron.yale.edu/ftp/neuron/papers/effic84.pdf I've been thinking about how to prove second or...

Maintaining Second Order Accuracy at Branch Points

I've been trying to learn more about the implementation of NEURON, so far working through the discretization of the neuron and relevant equations to have second order accuracy in space and time. The cables were easy to prove second order accuracy with using Taylor's Theorem, The NEURON Book , and "E...
