Re: Diameter of a Squid Giant Axon Model
Woww! This is going into deep waters. But yeah, I got the idea of why the oscillations happen. Thank you once again for your quick and informative reply as always. So, the perceived inductance is not real, the oscillation is caused by the involvement of active channels, huh! I tried the experimental...

Re: Diameter of a Squid Giant Axon Model
Thanks, this makes sense now. I have one more question regarding squid axon behavior (not sure if I should post it as a separate post in the forum). When I use the default HH axon (L=100, diam = 500, celsius = 6.3) and stimulate it with a step current (IClamp, amp = 1, delay = 1000, dur = 300), I ge...

Diameter of a Squid Giant Axon Model
Hello everyone, when you create a new section in NEURON, the default length of the section will be 100 um, the diameter will be 500 um, and the temperature will be 6.3 degrees Celsius. I guess this is in accordance with the properties of squid giant axon. But then why do the dimensions in the "...

Re: What is a NEURON equivalent of a point-neuron?
Thanks a lot for your clarification. I wasn't very thorough with the experiment. There was a mistake in evaluating the area as well. I included the flat surfaces of the soma for the computation. It seems only the curved surface area of the cylinder is involved in the ion conductance - is that so? Ea...

What is a NEURON equivalent of a point-neuron?
It is possible to define a dimensionless point neuron without using NEURON simulation environment as below: import numpy as np from scipy.integrate import solve_ivp # Define the Hodgkin-Huxley model parameters Cm = 1.0 # membrane capacitance (uF/cm^2) gNa = 120.0 # maximum sodium conductance (mS/cm^...
