```I am not studing biological NN.  I guess the answer may be found in
complex number domain which is studied in mathematics.
When a spike of 75mv comes, it must spent a piece of time from 0mv to 75mv
and
take some time from 75mv to 0mv. The second spike is same.  So we can
calculate
the sum of the two spikes, to find the time point when the sum is over
100mv.
And then determind which synapses get more strengthened.
All the above statements maybe wrong.  I hope it will give you some hints.
