parallel simulations of networks
On 12/1/2004 Ulf Knoblich <knoblich@csail.mit.edu> asked: we're thinking about simulating a large network of "biological" neurons (as opposed to "artificial" ones), i.e. neurons with membrane currents etc. Has anyone ever tried to distribute computations over a cluster using NEUR...

A variable must be declared to be an objref before it can be used as an objref. Objrefs must be declared at the top level of the interpreter. Statements that appear within a proc or func are not at the top level of the interpreter. So this works objref fap proc foo() { fap = new Classname() } but th...

How to use random numbers from within a mod file?
On 4/21/2005 Luca Finelli <lfinelli@salk.edu> asked:
What's the best way to have a random number generator available
inside a mod file (can one use the syntax for Random in hoc files?).

If your model has no ion accumulation mechanisms (diffusion, buffers, transport mechanisms), ionic equilibrium potentials are treated as constants and are specified with simple assignment statements. When there is an ion accumulation mechanism, the affected ionic species becomes a state variable in ...

It can contain as many different kinds as you like. If your net has only a few cells, you can do the whole thing with the Network Builder (see tutorial at http://www.neuron.yale.edu/neuron/docs ). If your net has > 5 or 6 cells and many synaptic connections, use the approach described in chapter 11 ...
