Adding a spine correctly
Posted: Mon Dec 14, 2015 7:27 am
Hello,
if I want to add a spine with a neck of (for simplicity) 0.5 µm diameter and 2 µm length and a head of 1 µm diameter and length, I would naively use the following commands:
The resulting area should be 2 * Pi, however area(0.5) (with nseg = 1) gives me 6.8722339.
I guess this is some problem of Neuron wanting to treat all information as frusta, but the problem is that I need to have the spine in NEURON having exactly the same surface area as calculated in Matlab, so any idea how I could do this correctly?
Thank you very much.

Code: Select all
create spine
pt3dclear()
pt3dadd(0,0,0,0.5)
pt3dadd(2,0,0,0.5)
pt3dadd(2,0,0,1)
pt3dadd(3,0,0,1)
