| Outline of Final Research Achievements |
Brain glucose uptake plays an important role in brain function (e.g. cognitive function). To explore the mechanisms of brain glucose uptake, we examined the effects of insulin and exercise on brain glucose uptake. Administration of insulin into blood or lateral ventricle had no effect on brain glucose uptake. On the other hand, 30min of moderate intensity exercise increased glucose uptake in each brain tissues (cerebellum, brainstem, hippocampus, hypothalamus), while 120min exercise did not increase them. Thus, it is unlikely that insulin increases brain glucose uptake. In addition, exercise increases brain glucose uptake, while exercise-induced increase is suppressed when exercise is prolonged.
