Evaluate with localobj

I'm trying to execute the following: // $s1 is the name of a cell type proc method() { localobj str, cell str=new String("cell=new ") sprint(str.s,"%s%s",str.s,$s1) sprint(str.s,"%s%s",str.s,"()") execute1(str.s) . . . } This will work of cell is not a localob...

Hi Ted. I do not want to update variables with every fadvance. The trigger is a change in membrane potential originally triggered by a spiking event. In the case of backpropagating action potentials, the spike will radiate from the soma to the dendritic segments as a spiking event, similar to a line...

Ted, I think I understand your concern, because as I start to delve into the NetCon class, I'm up against a wall and it appears that I will throw the baby out with the bathwater because I do not see how to modify the weight vector of NetCons dynamically. I want a dendritic segment to be able to broa...

Thanks for the replies. What I will be evaluating is dendritic branches that backpropagate action potentials and receive IPSPs. (The mitral cell). IPSPs received on one dendrite can prevent the action potential from backpropagating along the remainder of the dendritic branch. It is this behavior, in...

multi-compartment artificial integrate and fire cells

I need to construct artificial/LIF cells with event-driven dendritic trees and I would like to get feedback on the appropriate strategy. My current thought is to have two objects: Some LIF object and DEND_SEG, a segment of dendrite. My meta-object cell would use the LIF as its soma and then I will c...

Automake version?

I have added code to neuron and need to re-run aclocal, automake, and autoconf. (I even tried autoreconf). Everything seems to compile okay, but on install, I get a directory called "@host_cpu@" instead of "i686". When trying to launch the program, it does not work even if I chan...

Loading mechanisms without a gui?

Hey all, I am wanting to run neuron without a gui. I can launch via nrniv my_init_file.hoc However, this does not seem to find or load my NMODL files and I get "undefined function" errors from functions that are in these NMODL files. If I call nrngui my_init_file.hoc , then these additiona...

Stacked, multiple plots?

I would like to perform a run and plot the results. I then want to make a change and perform another run. I want to see the results of my first run on one graph, and the results of my second run on another graph, aligned with my first run, but below it. Preferably, I'd like these graphs to be in the...

I am modifying parameters then running my simulation to see if the neuron fires at a particular number of times during the simulation. If it becomes apparent that the neuron will not be able to attain the number I'm looking for, I'd like to abort. Note, this is a biophysical model.

Analyzing vector during record?

I am doing some batch processing, recording a vector during each run. During the run, I would like to periodically analyze the vector being recorded to determine if I can abort the particular run instead of having it run to completion before analyzing the vector. Is this possible? How?

Thanks,
Tom
