Outline of Final Research Achievements |
Adaptive information processing in biological systems is carried out by complex network systems such as neural networks and gene regulatory networks. Therefore, understanding the relationship between network structure and information flow is essential for understanding information processing in living organisms. We have developed a theory to describe information flow using information transfer pathways called paths, and presented it in a paper. We also generalized the input signals applicable to this theory, which revealed how the information flow depends on the characteristics of the input signals. This was also published in a paper.

Academic Significance and Societal Importance of the Research Achievements |
川の流れや電流の総量は各経路の流量の和で捉えることができるが、情報の流れはそうはいかない。このため、ネットワーク上の情報の流れを理論的に記述することは一般に難しい。我々は、ネットワーク上の情報流を情報伝達経路同士の掛け算の和で記述する理論を構築することに成功した。さらに、この理論を使って、入力シグナルの特徴と情報流の大きさとの関係性を明らかにした。これらの成果は、環境が変わると振舞が変わる生物系を理解する上で、重要な手掛かりを提供すると期待される。
