Motor learning is a basis for the physical rehabilitation. The spaced training efficiently forms long-term memory compared to the massed training. The existence of spacing effect in memory mechanisms indicates the importance of the inter-trial-interval (the rest). The mechanisms underlying long-term during the inter-trial-interval, however, is largely unknown. In this research, first, we established the long-term adaptation of optokinetic response as a simple model of motor memory. Then, we demonstrated the 30 and 60 min inter -trial-interval works efficiently for the formation of the long-term adaptation. In addition, we analyzed reactive oxygen species-nitric oxide pathway as a potential system underlying spacing effect and identified components of the pathway in the cerebellum, the center of motor learning.
