| Outline of Final Research Achievements |
Myouga (Japanese ginger, Zingiber mioga) is one of the most popular potherbs in Akita Prefecture, however, it is said that it is easy to make forgetfulness when you eat too much Myouga. But there is no scientific evidence on the relationship of Myouga and forgetfulness. Rather, there is a report that the α- pinene, which is the essential oil component included in the Myouga, suppresses the activity of the sympathetic nervous system and makes the relax states.
In this study, functional brain imaging method using near-infrared spectroscopy, that is easy to measure and evaluate the cerebral blood flow of the prefrontal cortex, was applied to examine the effect of α-pinene gives to working memory. Working memory is a system for temporarily storing and managing the information required to carry out complex cognitive tasks such as understanding, learning, and reasoning.
