Need help on synapses.

My training is largely in computer science, and I know little about
neuroscience. My questions might be easy (or just commonsense) for
you neuroscientist. Please take a few minutes to help me with the
Suppose that we have two neurons with synapses in between the two neurons.
We feed an electric pulse into the presynaptic side of a synapse, and we get
a pulse from the postsynaptic side.
I need to know if all the synapses in between the two neurons have the same,
similar, or quite different response (postsynaptic pulse) with the same input
pulse at presynaptic side.
If we take out different pairs of neurons from a part of the brain, such as
hippocampal neurons from a rat, I need to know if synapses from different
pair of neurons are different.
So the question can be reduced to: Are the synapses in the same functional
region of the brain homogeneous ? If not, how different are they ? It seems
to me that if they are quite the same, they don't process information much.
I might be wrong. Thanks.
Any information would be greatly appreciated.
