I have changed my text editor to IDM UEStudio, because I can modify it to show a function list, also it has a better syntax highlighting. Text Folding is active in this text editor for hoc code. To activate syntax highlighting in this text editor, go to advanced menu -> configuration -> Editor Displ...

We have a section for gui and a section for python, but no section for hoc. I think it would nice if there was a section for hoc programing in the forum.

When I was trying to execute this example in the List class documentation, I have noticed some strange behavior. I just want to make sure this is a normal behavior. When I select an Item in the A[0] class (for example Random[1]) Neuron prints item 2 selected in list of object A[0] which is a normal ...

explain more, please. I don't get what you mean.

Gerstner09 [How Good Are Neuron Models]
See this new science journal article. To be honest, I didn't know that integrate and fire neuron model have the potential to be a good approximation of a real neuron even better than compartmental ones.

I was trying to use map_segments_to_3d() procedure originally writen by Terrence Brannon, to assign each nseg a unique 3D address. this is the code: : 3-D mapping of model geometry NEURON { SUFFIX d3 RANGE x, y, z } ASSIGNED {x(micron) y(micron) z(micron)} load_file("morphology.nrn") foral...

1) why most authors neglects these kind of synapses? 2) Using these detailed synapses has a positive or negative impact on the model’s validity? I asked my questions from Nelson Spruston Before I start this topic. he answered my question, today: the short answer is that most people prefer simpler m...

The equivalent-cylinder model is a useful construct for studying the effect of current input or a voltage clamp applied at the soma on voltage changes throughout the dendritic tree. Its simplicity allows mathematical analysis and ready insight into dendritic function. However, it is less useful for...

Extracellular resistance is usually assumed to be negligible in models. While this is clearly not true (because extracellular recordings could not be made otherwise and ephaptic coupling has been observed among tightly packed neurons; Jefferys, 1995), it is a reasonable assumption in most situation...

when I was reading my new book "Computational Modeling Methods for Neuroscientists" I found a piece of information about reciprocity in it. Passive systems exhibit a nonintuitive symmetry in voltage responses called reciprocity (see discussion in Major et al., 1993). The voltage response a...

on the head of synaptic spine, there may be only a few dozen channels and so it becomes questionable whether to treat the fraction of open channels as a continuous variable. Rather, we may have to treat each species or channel as a random individual. The randomness arises because the opening and cl...

I decided to start this topic and include every piece of information I find in this regard. It may help other people after me. To start I refer you the one nice article I find. (Excuse me If I have my own referencing method - this method seems to be enough for at least 100 years which is enough for ...

Fairly striking examples of reciprocity are presented in Fig. 9 A and B of Magee, J.C. Dendritic hyperpolarization-activated currents modify the integrative properties of hippocampal CA1 nyramidal neurons J. Neurosci. 18: 7613 - 7624, 1998 This example shows the reciprocity of Dendrites in response...

Calm down please. 1) I just want to say that there is some oversimplification exist in articles. some times we used to some common simplifications and forget to reevaluate them in new situations. 2) If I was sure about what I am saying then I did not decide to consult with experts. I just want to or...

The premise is faulty. How do you know that anybody "try to neglect"? Most, if not all, probably consciously decided that such details are largely irrelevant to the hypotheses that motivated their models. I think for most authors it is enough to reproduce their experimental result with th...
