We study a network of FHN oscillators with all- understood through the behax to—all synaptic coupling described by Alfa functions and analyse the changes induced by noise in its synchronization patterns. The noise, added in the equation A neural systems ofthe fast voltage va riable, is assumed to be Gaussian uncorrelated. A variety of different noise effects is found depending on the sign and the time scale of the synaptic current. Tipically the global synchronization reaches a changes constant level for networks of justafew oscillators.
