The neuroplastic effect of olfactory training to the recovery of olfactory system in mouse model.

OT improved olfactory function, as indicated by the food-finding test. OT improved the olfactory recovery time to stimulate olfactory nerve regeneration. OT may initially stimulate the olfactory receptor, followed by neurogenesis. Steroid therapy and OT operated under completely different mechanisms in the upregulated gene study. These results indicate that OT may be one of the future modalities for treating olfactory impairment.
