Research topics: The function of ornithine underlying sexual dimorphism of sleep in hydra

Keyword

Summary: Sleep is not only a physiological phenomenon that exists only in vertebrates, but also in so-called lower animals such as Drosophila and nematodes. Our group discovered that sleep is even present in the cnidarian hydra, which belongs to a group of animals that evolved before the acquisition of the brain. However, it has not yet solved the essential question, "Why did animals need sleep?" We are trying to answer that question by elucidating the sleep control mechanisms of hydra.
In this study, we focus on the difference between male and female in the amount of sleep of hydra. We are trying to find out the reason why sleep is necessary for animals by elucidating the molecular mechanisms underlying ornithine-induced sexual dimorphism in hydra.

Message

Sleep regulation is very complex. We are trying to simply elucidate the sleep mechanisms using Hydra. We would be happy if our research can contribute to the understanding of sleep regulation in higher animals, including humans.
