Hierarchical dual memory structure determines cognitive logic of the human brain

The present work provides a cognitive model revealed by the physiological structure of the human brain. A hierarchical dual memory structure underlies cognitive logic processing. Perceptual memory receives information from the physical world and represents physical information with a one-to-one correspondence. Conceptual memory receives information from the perceptual memory with a one-to-one correspondence. Induction is the acquisition process that relations are learned and memorized in between the two memories as knowledge. Deduction is the retrieval process from the perceptual information to its conceptual relations. Reduction is the retrieval process from conceptual information to its perceptual relations. This biological model has been applied as a computational model of the nondeterministic Turing machine successfully, which will be published separately.
