Takeuchi Lab
Machine-translated · View original
A lab that explores the mechanisms of perception, emotion, and memory through the mouse sense of smell.
AboutAbout the lab
Decoding how the brain works through odors.
The Takeuchi Lab studies the mechanisms of perception, emotion, and memory, using the mouse olfactory system as a model.
Using methods from molecular biology and neurophysiology, the lab investigates at the cellular level how neural circuits are formed and how they function.
The lab observes and manipulates neural activity using electrophysiology, calcium imaging, and optogenetics.
Based on scientific evidence, the lab also explores strategies for preventing and treating neurological disorders through odors.
Key terms
- Neural circuit
- A pathway formed by neurons connecting to one another, through which information is passed along
- Calcium imaging
- A method of studying neuronal activity by using light to visualize the calcium that increases when neurons are active
- Optogenetics
- A method of switching the activity of specific neurons on and off by shining light on them
ResearchResearch themes
Using the mouse olfactory system as a model, the lab aims to elucidate the mechanisms of perception, emotion, and memory with methods from molecular biology and neurophysiology. The lab also explores evidence-based strategies for preventing and treating neurological disorders through odors.
*Illustrative imageHow neural circuits are formed
Using the mouse olfactory neural circuit as a model, the lab aims to understand at the cellular level how circuits are formed, and how they process information to give rise to behavior.
*Illustrative imageHow odor perception works
The lab observes neural activity one cell at a time using electrophysiology and calcium imaging, and combines this with optogenetics to examine how responses to external stimuli change with experience and context.
*Illustrative imagePrevention and treatment with odors
The lab has independently developed a system that exposes mice to dozens of types of odors over long periods, and uses multiple behavioral tests to comprehensively examine how odors affect neurological disorders.
