You're quite welcome. Sooner or later, you probably would have figured this out
on your own anyway.

How to find spike threshold automatically
nrn/lib/hoc/thresh.hoc implements a binary search that can be quite useful for finding spike threhold. Read the source code to understand the details, but basically it adjusts a user-specified variable and uses an APCount to detect the spike. Here's an example of its use: 1. Create a file that conta...

Re: A beginner follow-up question
I'm trying to plot the individual contributions of an hh channel model and an m-current channel to the total k current vs time. For the 19th PY cell, using the Plot what? tool, the total k current might be "PY[14].soma[0].ik(0.5)." True. Assuming that the suffix for the NMODL M-current ch...

CPU usage (as reported by the Task Manager) never gets higher than 55-60%. NEURON isn't the only program that is running. What else is Windows doing? If you want the CPU to spend more time on a particular program, you have to increase that program's priority. Presumably Windows allows you to specif...

Conductance density is in units of conductance/area, so total conductance is the product of area and conductance density. To find the number of channels required to produce that total conductance, divide total conductance by the conductance per channel. The arithmetic is similar if you are dealing w...

Source code and errata for FCTB
I should point out that Bill Lytton has posted the source code for the models and exercises
in his book "From Computer to Brain" on NEURON's WWW site--see
http://www.neuron.yale.edu/fctb/
A pdf that contains a list of errata is also downloadable from that URL.

There are several errors in the USEION statement, but It's not clear to me why you are bothering with a USEION statement at all. Is your model going to include an accumulation mechanism for this new ionic species? Are there other mechanisms that will affect, or be affected by, the concentration or e...

Re: 3D points of a segment
Does point (x1,y1,z1) correspond to the "0" end of the segment and (x10,y10,z10) correspond to the "1" end of the segment? First a word about terminology. Segments do not have 0 or 1 ends. In your code example, a is a section, and its 0 and 1 ends are at x1,y1,z1 and x10,y10,z10...
