For the paper:

Fast Global Oscillations in Networks of Integrate-and-Fire Neurons with 
Low Firing Rates. Nicolas Brunel & Vincent Hakim
Neural Computation 11, 1621-1671 (1999)

a brian simulator model is available at this web page:

http://briansimulator.org/docs/examples-frompapers_Brunel_Hakim_1999.html

That reproduces an example of Figure 3C



This simulation requires Brian which can be downloaded and installed
from the instructions available at http://www.briansimulator.org/

For support on installing and using Brian simulations there is a
support group at https://groups.google.com/group/briansupport.
