Hi Luc
Thank you for the response. The example file that you mentioned is correctly for a modulated connection. This example however is using an error signal that is computed by an error-ensemble. I am purely interested in using the STDP learning rule, as described a bit further down in the Bekolay paper. This learning rule was first described by Pfister and Gerstner and takes the parameters, t^pre, t^post1, t^pre2, A^-_2, A^-_3, tau_- and tau_x. The learning rule itself takes the form of
              
This learning rule is supposedly already implemented in Nengo, I am just not able to use it, as I am unaware of how to create a connection that is modulated by this rule and not the normal error-ensemble modulated connection.
Regards

Hi Claus,
you can find a well working coding for such a connection in the 'Build a Brain' folder, chapter 6, 'learn.py'. It opens in wordpad.
Chapter 7.5. "Nengo: Advanced Modeling Methods", p284 in 'How to Build a Brain' by C. Eliasmith, gives you a lot more practical tips.
Success,
Luc Vanneste
