Action Potential propagation
Posted: Sun Mar 15, 2020 2:06 pm
Hi,
I have 3 questions:
1: Would you please tell me, the model that NEURON uses is always based on cable theory ? Can we have point model of neuron ,too?
2: I wrote this code:
create soma, axon
access soma
soma.nseg = 1
soma.diam = 18.8
soma.L = 18.8
soma.Ra =123.0
soma insert hh
soma psection()
axon.nseg = 1
axon.diam = 18.8
axon.L = 500
axon.Ra =123.0
axon insert hh
axon psection()
connect axon(0),soma(0)
objectvar stim
soma stim = new IClamp(0.5)
stim.del = 100
stim.dur = 100
stim.amp = 1
tstop = 300
and I want to see action potential propagation along the axon, so I plot axon.v(0.1) and axon.v(0.9) and I expected to see a time delay between spikes that I didn't see.
Could you please tell me how can I fix this problem?
3. And my last question is how can I compute intracellular voltage Vi = Vm + Ve ?!
Thanks
