Adding multiple synaptic connections to the two-compartment model (Ladenbauer 2019)

Hi, Two months ago, I implemented the two-compartment model (Ladenbauer 2019) in Neuron. Here is the link to the last post regarding the implementation: https://www.neuron.yale.edu/phpBB/viewtopic.php?f=18&t=4370 . The model uses its own variables vs and vd for the transmembrane potentials at so...

Re: How to model spike and reset condition Ladenbauer 2019

Hi Ted,

I found the issue in my code and fixed it. "WATCH (vs>vt) 2" should be "WATCH (vs>vth) 2". Thanks.

Re: How to model spike and reset condition Ladenbauer 2019

Hi Ted, Thank you so much for the help! I managed to solve the issue. Vs resets to Vr (0 mV) after passing VT (10mV). Now I have some problems with setting Vs to Vth (20 mV) before resetting. I suspect there is something wrong with my NET_RECEIVE block. I set Vs to Vth after passing the VT but it wo...

How to model spike and reset condition Ladenbauer 2019

I am interested in writing the two-compartment neuron model (Weak electric fields promote resonance in neuronal spiking activity: Analytical results from two-compartment cell and network models,2019) in NEURON.

How to model synaptic activation using NetCon

Hi,

I want to model the synaptic activation in Neuron. I have one neuron connecting a second neuron with AMPA synapse using NetCon. Is there a way to activate the synaptic connection without making the presynaptic cell fire? Can I just feed a spiking event to NetCon? Thank you.

Modeling leaky integrate-and-fire neuron including Hodgkin–Huxley-like currents

I have constructed a MOD to model leaky integrate-and-fire neuron including HH-like currents from the paper "Modeling the Effects of Transcranial Magnetic Stimulation on Cortical Circuits". The link to the paper is: https://www.physiology.org/doi/full/10.1152/jn.01230.2004?url_ver=Z39.88-2...
