Synchronization in a pair of non-identical
integrate-and-fire oscillators coupled with exponentially
relaxing excitatory stimuli is studied analytically as well as
numerically with the focus on 1:1 synchronization. It is found
that when the relaxation time τ of each stimulus is finite,
increasing the coupling strength causes desynchronization in some
parameter range. Scaling behavior of the phase boundary of
synchronization is also found for 
and
