Neuroethology Lab
Machine-translated · View original
A lab that explores the significance and principles of sleep in mammals and lizards.
AboutAbout the lab
Understanding life through sleep research
The Neuroethology Lab studies the mechanisms of sleep, aiming to clarify the "significance" and "principles" of sleep.
In addition to mammals such as mice, the lab uses bearded dragons as a model animal.
The lab carries out its research with a variety of methods, including electrophysiology, pharmacology, molecular biology, and behavioral observation.
The lab also investigates memory consolidation during sleep and the relationship between circadian rhythms and brain disorders.
Key terms
- Bearded dragon
- A reptile (called futo-agohige-tokage in Japanese). The lab uses it as a model animal for sleep research, and it has both REM sleep and non-REM sleep.
- ripple
- A brain wave generated in the hippocampus. It has been found to organize memories during sleep.
- Circadian rhythm
- The mechanism that regulates an animal's body so that it operates on a rhythm of about 24 hours.

*Illustrative imageHow sleep arises
Using mammals such as mice and bearded dragons, the lab investigates the mechanisms of sleep in detail. In bearded dragons, REM sleep and non-REM sleep alternate regularly in very short cycles, which could be a major advantage for studying sleep stages.
*Illustrative imageHow memories are consolidated during sleep
It has become clear that ripples, brain waves generated in the hippocampus, organize memories during sleep. The lab pursues ripples to understand how memory works, and also investigates what in the memory system breaks down, and how, in disease model mice.
*Illustrative imageCircadian rhythms and brain disorders
Animals' bodies are regulated to operate on a rhythm of about 24 hours, and major changes occur in the brain. It has also become clear that the effects of a drug differ greatly depending on the time of day it is administered, and the lab aims to propose new treatments for brain disorders.
