Sorry Ted for not being clear. Yes, each is a section. One section(cilium) has a mechanism attached to it. This mechanism has 8 differential equations that signify various components of signal transduction. I have added one more section(cilium) to this model with the same mechanism. There are no err...

I have a neuron model with soma, dendrite and cilium. The cilium has a mechanism added that gives variation of 8 variables with time. I need to add one more cilium to this model. But, when I add 1 more cilium with the same mechanism, both the cilia show error in graphs of the variables after 0.5 sec...

Thank you Ted for the detailed reply. It really helped.

Thank you for the details, Ted. I have gone through the modeldb entry you indicated, But, this code has a POINT PROCESS which is accessed by 2 .mod files. Is there a way to interact between the 2 mechanisms directly, without the POINT PROCESS?

Thanks and regards

I have a mechanism that has a state variable cAMP. Is it possible to access this state variable in another mechanism (.mod file)? The second mechanism has a state variable depending on cAMP.

Thanks

Hello,

Adding to this thread, is there a way to call a Matlab user-defined function from .mod/ .hoc file? I am working on Neuron 7.7.2 and Matlab2019.

Thank you

I have mailed you the zip of the code. It can be used with a single compartment model. Thank you for your timely help.

I have changed to derivimplicit, but there is no change. I printed the values for the PROCEDURE formulas and found they are not being calculated. kG: -1.#IND, rG: -1.#IND t: 5, syncAMP: -1.#IND, Icng: -1.#IND, inhcng: -1.#IND, JNCX: -1.#IND, cc1: -1.#IND, ck1: -1.#IND, cx1: -1.#IND, IClCa: -1.#IND, ...

Thank you Ted for your reply. STATE block declares all of the variables on LHS of the ODE's. BREAKPOINT contains below code: BREAKPOINT { hv1 = 1/(1+(exp(-(t-1)/sharpness))) hv2 = 1/(1+(exp(-(t-2)/sharpness))) ipulse = hv1 - hv2 od = ostim * ipulse SOLVE blrrate METHOD cnexp printf("t: %g, blr:...

In my .mod file, I have 8 DEs to be solved, and all are interdependent. DERIVATIVE block is as follows: DERIVATIVE blrrate { calcParameters(blr, aG, cAMP, aCaMK, Vcilia, CaCaM, Ca, IX) blr' = k1 * od * (Rtot - blr) - r1 * blr aG' = kG * (Gtot - aG) - rG cAMP' = syncAMP - pd * cAMP Ca' = inf * Icng -...
