Unfortunately that won't work. The first declaration that a name is an objref must occur outside of a proc or func. Once a name has been declared an objref, it can appear in another objref statement inside a proc or func, like this objref ref proc p() { objref ref } If you really need to hide an obj...

There have been several attempts to come up with strategies for deciding how big a compartment shoudl be. Most of them are pretty useless. The only exception I know of is to make compartments shorter than some fraction d_lambda of the AC length constant at some frequency that is so high that most me...

One way to save the sequence of (x,y) coordinates to a file is to use the Print & File Window Manager (PFWM) to Print / Ascii. On the FAQ page http://www.neuron.yale.edu/neuron/faq/general-questions see the link called How do I print a hard copy of a NEURON window? You can also "pick" ...

Lots of good questions here. Some belong under the topic Adding new mechanisms and functions to NEURON--NMODL and the Channel Builder and others belong elsewhere. It may be didactically appropriate for me to come back and split up this reply. 1. I have done hippocampal CA1 network of 500 cells (sing...

1) I created a very simple network (2cells connected via one ExpSyn) with the network builder. Now I need to insert a point process (VClamp) at the presynaptic neuron, yet I can't find the created network cells in the point processes menu... Several issues here. 1. Point processes menu? What point ...

I WAQNT TO AMKE A PROJECT ON NEURON. I DIDN;T ANY IDEA ABOUT IT . HOW TO MAKE IRT SO PLESASE HELP ME.

Go to the FAQ (Frequently Asked Questions) page at NEURON's WWW site

and start reading.

NEURON does not have a notepad feature. You can use a graph's Change Text feature to add brief comments to it before printing or saving it to an idraw (postscript) file--click on the menu box and select Change Text. Then click on the canvas and type anything as long as it fits on a single line. Brea...

Chapter 11 http://www.neuron.yale.edu/ftp/ted/book/revisions/chap11indexedref.pdf shows how to use the hoc file emitted by a NetWork Builder to create a large net. An indexed version should be available in a few days, but the narrative is linear and cumulative, so lack of an index should not be a se...
