Re: Three questions on extracellular stimulation and recordi

I know what you mean. In your opinion, "my model" means the model I work with. While, in my opinion, "my model" means the model I want. I am doing some research on computational neuroscience and want to use Neuron to validate my numerical method. Since I happen to read the aforementioned paper first...

Re: Three questions on extracellular stimulation and recordi

The resting potential in my model is always -60 mV.The parameter is from the following paper Celine Moulin, Alain Gliere, Danier Barbier, etc. A New 3-D Finite-Element Model Based on Thin-Film Approximation for Microelectrode Array Recording of Extracellular Action Potential. IEEE Trans. Biomedical ...

Re: Three questions on extracellular stimulation and recordi

Dear Ted, Thank you for your reply. The problem for "vec.record" and "file.wopen" has been solved. According to your suggestion, I add a "run()" statement in the program,which is shown below objref vec vec=new Vector() vec.record(&soma.v(0.5)) run() objref file file=new File() file.wopen("temp") vec...

Three questions on extracellular stimulation and recording

Hello,everyone! I am simulating the extracellular potential recording with extracellular stimulation by NEURON and have three questions. 1. I found a relative program on extracellular stimulation and recording with -65 mV resting potential on NEURON website. Since the resting potential in my model i...

Questions on extracellular stimulation and recording

Hello everyone! I am a new hand and doing some research work on extracellular recording with extracellular stimulation by NEURON, and have four questions as below 1. How to simulate bi-polar extracellular voltage stimulation with GUI. 2. How to simulate bi-polar extracellular voltage recording with ...

rho / (4 PI r) is the resistance that you would measure if you placed a spherical electrode of radius r in an infinite conductive medium with resistivity rho, and attached your ohmmeter's electrodes to the sphere and he "container of the infinite conductive medium." Thus, since rho / (4 PI r1) is t...

Thank you very much. Your answer is very useful for my farther learning. However there is still confusing about the meaning about variable r As you mentioned rho / (4 PI r) is the resistance that you would measure if you placed a spherical electrode of radius r in an infinite conductive medium with ...

some questions about extracellular stimulation and recording

Hi all, I have just begun to learn to use NEURON and read the Extracellular Stimulation and Recording program downloaded from http://www.neuron.yale.edu/ftp/ted/neuron/extracellular_stim_and_rec.zip . Now I have six very primary questions: 1 nesg is decided by d_lambda rule. In other words nesg=int(...

Dear Ted, My name is Lewis. I'm a new Neuron user and working with the 6.0.4 version of Neuron on Windows XP. Now, I am doing some research work about spinal cord stimulation, i.e. using cuff electrodes in epidural space to stimulate the nerve in spinal cord for restoring given function. I have used...

a question about extracellular stimulation

Hi all, I have just begin to learn to use NEURON and have a very primary question. I am trying to apply the extracellular mechanism to a series of nerve cell. I want to simulate voltage-controlled extracellular stimulation, so I am giving to e_extracellular potentials values that correspond to field...
