Modeling axonal propagation delays

["Antonio M. Rodriguez" <tonyr@uci.edu>]

Hello everyone,

I'm trying to model both short and long distance connections in a
network.  Unfortunately, I can't find an elegant method for modeling
fast versus slow arrival times of neuronal activation.  I've tried using
connection weights but I don't want to affect the magnitude of the
incoming signal.  I just want it to be delayed in the case of the long
connection.  I also tried making the sending neurons of the long
connection take longer to fire but this isn't really what I want
either.  Someone suggested that I use a domino effect of intermediary
neurons to propagate the activation signal in the long connection.  This
might work but the extra neurons would greatly slow down my simulation
and I still think there must be a more direct approach.

Any suggestion would be greatly appreciated.

Thanks,
Tony Rodriguez
