integrate and fire model

hey every one
Actually I would like to know what is the function of integrate and fire model in matlab,this model/function convert the picture into spikes.
furthermore ,my project about the blind people ,so what we are doing is we are taking a picture and we do some filters to it then we convert it to spikes ,then we can send it to to the eye through the brain ,so the blind people can see.
The integrate and fire model generate's these spikes ,if any one can help me I would really appreciate it.
Thanks

This is a very specialized niche application so it's highly likely
that no one monitoring this newsgroup will have done anything like
that. Personally I've never heard of the "integrate and fire model."
Why can't you just translate the algorithm from the math in the paper,
or wherever you saw this, into MATLAB code? That may be the only way
because I doubt someone here will say "Oh, here, take my integrate and
fire code - it's ready to go!" I could be wrong though.

Thank you man for replaying,I am asking because my professor told me there is a function that do that and I don't to do all of it from scratch.

OK a web search seems to indicate that it's some kind of a neural
network concept. I don't work with neural nets, just images, but some
people here do. Hopefully someone with the Neural Network Toolbox
will answer you.

Sorry, never heard of that model, and never done any neural net work. If
you were to describe what you are trying to do or the math behind it in
more detail, then it might be easier for people to help you. It isn't
uncommon for the same concepts to show up in different areas of studies
under other names.

Just using the term "integrate and fire" is too vague.

Please be more specific.

Hope this helps.

I think he specifically means this:
http://icwww.epfl.ch/~gerstner/SPNM/node26.html

Saied, I doubt there is a single Matlab function which will do this. Although as it happens, someone has uploaded an HH simulator, so that should help:
www.mathworks.com/matlabcentral/fileexchange/27209-hodgkin-huxley-like-model-neuron

On a different topic--what are you doing exactly? From your description it sounds like you may be planning on delivering spikes extra-cellularly (presumably to ganglion cells). Is that the case?

I googled "integrate and fire matlab" (without quotes) and the very first link tells me how to build an integrate and fire neural model in Matlab! Have you looked at that?

Dear Mr Saied,

i'm interested with your work...i'm now dealing in this area and having the same difficulties as yours...have u solve your prob?..i managed to write integrate and fire in matlab..but i don't have an idea how to integrate it with the input image..pls help me on this..
