Delivering stimulation includes delivering temporal patterns of stimulation pulses to respective transducers of an array of transducers, wherein the delivery of the pattern to a particular transducer of the array is different from at least some of the deliveries of the patterns to the other transducers of the array at least according to a time delay. The patterns delivered may include regular temporal patterns each having a respective constant inter-pulse interval. The constant inter-pulse intervals may be about the same. The patterns may be staggered. The transducers may deliver electrical, optical, acoustic, thermal or magnetic stimulation.
