My research topic is “Investigation on the brain penetration of oxytocin through Intranasal administration using mouse”. This study investigated the effects on the brain after intranasal administration of oxytocin and the route of oxytocin proceeding. Ultimately, it was found that intranasal administration of oxytocin can be delivered to specific regions of the brain in the case of using a mouse model. For the future, I hope that I can continue to have research on Alzheimer’s disease as a researcher in a corporate research institute or in a research organization.
