connection of two neurons

Please tell me what is the error? The code below has a template with soma, axon, apicular and basilar dendrite. Two copies of this template are made to get two neurons. Here one neuron ca[0] is the source neuron and ca[1] is the target neuron. I have connected the two neurons in one direction only, ...

Re: use of Netcon weight

This code has a template having 2 apicular and 1 basilar dendrite along with a soma and axon. The template is used to have two bidirectionally connected neurons. Also two current stimuli are given to each of the soma. load_file("nrngui.hoc") begintemplate CA1 public soma, axon,ss public sb1 public s...

use of Netcon weight

[quote][How does the netcon.weight change the amplitude of the action potential generated or the epsp generated
also till what decimal place can I write netcon.weight, what is the minimum permissible value

Re: how to connect 2 neurons

[quote][ also I am trying to observe EPSP in the dendrite of the post synaptic or target neuron but I either see no voltage or an Action potential is generated. Why does this happen /quote]

Re: how to connect 2 neurons

I have injected current as per your suggestion in the soma using IClamp. Now i am looking for modl files for the NMDA-Ampa and channels to be placed in the dendrite of the neuron where will i find those. I am trying to best replicate CA1 neuron so I also want to know which all channels I need to add...

Re: how to connect 2 neurons

[quote] [The diagram is only a schematic representation as I could not paste the shape plot of my model. It has two neurons, one of the two neurons is named source neuron while the other is named target neuron. Each neuron has three sections namely dendrite, soma and axon . The title of the paper is...

Re: gui interface

My sincere apologies for the late feedback .Thank you for the suggestion.So far we have successfully connected two bidirectionally coupled neurons.

gui interface

[quote] i created two neuron model using gui, the 2 neurons are identical , with one dendrite , one soma and one axon . We placed 2 synapses one on axon and other on dendrite in both cells , hence we knew the exact location in target cell i.e either synapse on axon or dendrite, But how do we know wh...
