Can category theory bridge the gap between subjective experience and brain activity?
In short: Naotsugu Tsuchiya explores whether mathematics can decode the mystery of qualia—the internal 'what it is like' of experience. By using category theory, he seeks to map how different levels of sameness connect our private inner lives to their physical neural substrates.
The central challenge in consciousness science is relating subjective experience (qualia) to the physical brain. Tsuchiya proposes that we may not need two experiences to be identical for them to be meaningfully comparable. Instead, he utilizes category theory to characterize various degrees of similarity and structural relationships.
This approach allows researchers to move beyond simple correlations toward a formal framework for how conscious structures relate to their underlying biological mechanisms. It offers a potential mathematical language to describe the transition from neural firing to felt experience.
