Re: How to integrate synapses such as GABA and others...

I'm working through one of Destexhe's network model, he wrote hoc code for the whole program. I'm trying to repeat most of the part using NEURON GUI. (As a way to optimize the use of the GUI and write less code). He has a mod file for GABA_A, which he used as a synapse to connect the two cells. I sa...

How to integrate synapses such as GABA and others...

Please how can I interface synapses such as GABA (mod file) and other synapse into the NEURON gui so as to use them in networkbuilder for constructing networks?

Thank you

Re: Course: Using ModelDB Mainen and Sejnowski 1996

I did not write any code. I simply followed every instruction.

I have recompiled the mod and restarted NEURON and there was no problem.

Thank you

Re: Does it make a difference if a single compartment is soma or

I have played with ipulse1 you referred me to, I am able to generate the number of pulses I want. Thank you! But this raises more questions. I first defined the Pulse1a (the name I gave it) as a point processor ()IClamp in my hoc code (in a single compartment, soma). When I ran the code , the action...

Does it make a difference if a single compartment is soma or

I know soma is used to build single compartment model. I am working through the on-line course (handson), HH axon. The instruction is to create axon with given specifications, and insert current pulse. Here is my code create axon access axon axon { nseg = 75 diam = 100 L = 20000 insert hh } objectva...

Thank you again. I have tried several times to make the NMODL (listing 11.1) several times, merticously tying eacg letter as it appears in the list ing, this error message comes up always. Under INITIAL, t0 =t, and similarly under NET_RECEIVE. I don't know if that is why it says to is undefined. Tha...
