Fitting a phase plot.

I have two spike phase plots, that I have fitted visually and placed in the same grapher box. I read this phase plot fit topic, but I am not sure a polar plot is the solution. https://www.neuron.yale.edu/phpBB/viewtopic.php?f=23&t=1190 Each phase plot is composed of a bunch of points, which make a s...

Re: Choosing a CPU to speed up computations on single neuron

OK Ted, Here is my NEURON simulation speed CPU report from 2.13 GHz Intel 2 Core Duo 8GB ram, WIN XP 32 bit. 2.9 GHz Quad Core Intel Vpro 8Gb ram, WIN7 64bit. 50 msec simulation at 0.0005 msec time step. Core 2 Duo =131 338 sec. =5.6 min . Quad Core i7= 131sec. = 2.2 min. So about a 2.6 f old speed ...

Re: Choosing a CPU to speed up computations on single neuron

OK, recall I said I was simulating a single cell. "CPU: Intel i7. 4 core Gen 4 e.g. 4790 is adequate but "so last decade," 6 core Gen 5 e.g. 5820 or 5930 is more "current," and 2 CPUs is better than 1 (the more cores, the better when it comes time to optimize or explore parameter space; also you're ...

Choosing a CPU to speed up computations on single neurons.

What sort of computer will most benefit my speed needs for Neuron computations? I work in a govt environment where computer choice is very limited. My NEURON simulations usually just involve one reconstructed cell with modified H-H channels, and I am looking at spiking patterns for about 200msec. Wh...
