you'd have to write some c++ code to do this in pdp++ -- it wouldn't
be particularly difficult -- you could just store the time delay in
the synapse, and the time of the last spike on the unit, and only send
activation when unit->spike_time + cn->delay_time ==
trial->current_time; Josh Brown (jwbrown@artsci.wustl.edu) is writing
a "real time" spiking unit model for pdp++ and may have already done
this, and if not his framework would be the best place to add it.  Josh?
