一言メッセージShort Message

We will establish a "health status" index for neuronal cells that will serve as a foundation for promoting cognitive function recovery.

本プロジェクトでの研究概要Outline of the research in this project

We aim to establish an index for evaluating the “health status” of neurons that support the brain’s reservoir function, and to elucidate the cellular mechanisms that contribute to cognitive function recovery. Neurons continuously alter their properties, such as connectivity and excitability, in response not only to external stimuli but also to internal physiological and brain states. Using model animals, we will visualize and analyze changes in neuronal properties associated with cognitive recovery through advanced imaging techniques.
Furthermore, we will develop technologies to enhance the neuronal property changes that are expected to facilitate cognitive function recovery. We will assess whether these enhancements lead to improvements in cognitive function at the behavioral level in model animals, and establish innovative technologies for controlling neuronal cell property with potential applications in medicine.

これまで主な研究内容Outline of main research so far

“Elucidating the neural basis of cognitive flexibility using advanced imaging techniques.”
Our real-world is composed of numerous elements and continuously changing. Considering all these environmental factors to make decisions or find optimal solutions far exceeds computational capacity of the brain. To overcome this difficulty, the brain narrows down the relevant elements and forms an internal model of the external environment based on limited information. As a result, we are able to act quickly, flexibly, and appropriately in response to our environment. However, the details of how internal models are formed in the brain and how they influence our decisions have remained unclear. To address this question, we have developed advanced imaging technologies and are uncovering how internal models are constructed and reflected in behavior.
