Re: Neuron code

Anyone can help me to do Na/K restoration process, which pushes the concentrations back to equilibrium, because right now the sodium and potassium go up at a certain time and stay constant. is there mechanism to push them back to the resting value.

Re: Neuron code

thanks for explanation. that means the basic equation is Fick's second law,because I am looking for the differential equation that has been used to find the concentration in nadifl. You can find it here:

Re: Neuron code

Did you mean that LONGITUDINAL_DIFFUSION
del C/del t=del2 C/del2 x
so it is just Fick's second law.

Re: Neuron code

Thank you for the comments. I meant can anyone check whether the result make sense or not. Yes, the mechanism enae and eke to calculate reversal sodium and potassium, and mechanism nadifl and kdifl to calculate sodium and potassium longitudinal diffusion ( I do not know the exactly the basic equatio...

Neuron code

I am new user to NEURON ,I am writing a code to stimulate an axon in the middle. the axon has sealed end at both side. I trying to track the concentration of Na and K inside the axon during action potential. geometry: L=1[µm] d=0.1[µm] cm=1 [uF/cm2] the initial concentration {nai0_na_ion = 12} {nao0...
