Re: Izhikevich neuron has no stable state

Hi Casper,

You are absolutely right.  It's a little embarrassing that I've missed this for so long.    I had a look at the Izhikevich article I used to implement the equation, and the Wilson book I used for Naka Rushton, and both differential equations have time in milliseconds.   Come to think of it, Neuron and Genesis default to milliseconds, and it seems to be a standard unit in computational biology.

So, the text in the Simbrain GUI should read "msec" instead of "seconds," since that's already what's assumed in all the Simbrain neuron models that are based on differential equations.  The mistake is just in that bit of GUI text.    Since all these models assume msec, you should be able to mix Naka Rushton and Izhikevich neurons without a problem.

I think this warrants an update to 2.0.  I'll try to fix a few other things too (like the Izhikevich default values), and perhaps even scrollbars in the data table.   I'll get to it as soon as possible and put the updated  "2.01" download on the website.

Thanks very much for raising these issues.
