Human brain stores tremendous amount of knowledge about this world, which is the foundation of language, thought, and reasoning. What’s the neural codes of knowledge representation? Is the knowledge “roses are red” simply the memory trace of perceiving the color of roses, stored in the brain circuits within color-sensitive neurons? The knowledge of objects the composition of their multi-sensory attributes? What about knowledge that is not directly perceived by senses, such as “freedom” or “rationality”? I will present some work from my lab that addresses this issue using cognitive, neuroimaging, and neuropsychological methods with healthy subjects, individuals with sensory deprivation (blind and deaf) or with brain damage. The findings point to a highly distributed system incorporating two forms of representations: sensory-derived (embodied) and language-derived (symbolic), spanning across different neural systems.
