Fuzzy More-Equal-Less Logic and Closed-Loop Coding-Decoding Control Semantics in Bio-Systems and Nanoinfotechnology

The aim of this paper is to show that informational control in bio-systems is possible only through the use of closed-loop coding-decoding (CL-CD) and that CL-CD is a common feature of all organized systems that induces the birth of semantics. The analysis of the nervous systems research data shows that the coding and decoding procedure uses nota binary logic, but specific logic based on the "more-equal-less" (M-E-L) principle. It is likely that similar coding principle is used in molecular signaling structures (cells and hormonal subsystems of organisms) and that the implementation of this is a kind of nanoinfotechnology. Non-categorical M-E-L logic is similar to fuzzy (Zadeh) logic and may be used for explanation of neurobiological and neuropsychological facts through systemic (holistic) functional organization of the nervous system and of new neuroinformational and nanoinfotechnological ideas.
