Aiming to improve the simulating degree of olfactory system model, optimizing problem of olfactory system model was researched. Considering obvious presence of electroencephalogram synchronization, if there was synchronization state of the model output or not was used as research aim. The research key included three aspects: (1) Optimizing index. The phase information of signals was used as object. Phase locking value was calculated to evaluate synchronization degree. The phase synchronization degree between model outputs was used as optimiz...
