FIS Colleagues: The questions raised in this post are highly provocative. From the perspective of physical phenomenology, it is necessary to identify corresponding illations between the electric fields of brain dynamics (such as EEG patterns) and the mathematics of electric fields / electro-magnetism. It goes without saying that such correspondences must associate the measured quantities with the theoretical quantities. In other words, the units of measurements of “brain activity" should be associated with Maxwell’s equations. In the philosophy of science, this is the basic distinction between traditional mathematical narratives as pure abstractions and APPLIED mathematical theories of explanations of scientific facts. My responds to these questions are based on the propositional functions and the formation operators of applied (organic) mathematics. TOPOLOGY AND BRAIN FUNCTION Arturo Tozzi Center for Nonlinear Science, University of North Texas 1155 Union Circle, #311427 Denton, TX 76203-5017, USA, and tozziart...@libero.it James F. Peters Department of Electrical and Computer Engineering, University of Manitoba 75A Chancellor’s Circle, Winnipeg, MB R3T 5V6 james.pete...@umanitoba.ca Questions. 1) Could we use projections and mappings, in order to describe brain activity? JLRC A propositional function is needed to associate the logic of the theorem with the physical phenomenology of brain activity. The bi-polarity of electrical particles that generate brain function make this task extra-ordinarily unlikely. 2) Is such a topological approach linked with previous claims of old “epistemologists” of recent “neuro-philosophers”? JLRC This question is not scientifically meaningful to me. But, see my comment on physical Kantianism below. 3) Is such a topological approach linked with current neuroscientific models? JLRC No. present-day neuroscientific models are all based on electrical particles and organized collections of electrical particles. 4) The BUT and its variants display four ingredients, e.g., a continuous function, antipodal points, changes of dimensions and the possibility of types of dimensions other than the spatial ones. Is it feasible to assess brain function in terms of BUT and its variants? JLRC I do not find a propositional function in this interrogative, so I respond in the negative. Physical phenomenology associated with brain dynamics are discrete physical events, such as ion transport and neuronal firings. But, of course, if anyone can find a way to associate continuous topological spaces with quantum electro-dynamics of angular momentum necessary for brain activity, then I would retract my opinion. 5) How to operationalize the procedures? JLRC: Current theories of neuronal activity consists of several logical forms of physical sublations from the electrical particles to the mereological propositional functions of the whole. Which physical phenomena is the theory seeking to “operationalize”? 6) Is it possible to build a general topological theory of the brain? JLRC Of course it is. It is just mathematics. One such general mathematical model was published and it appears to be mathematically sound. The [FIS] informational challenge is find correspondence relations between mathematical symbols and physical symbols such that the mathematical theory can be tested. The scientific challenge is to find causal pathways for physical phenomena, whatever the mathematical structure of the theory is. 7) Our “from afar” approach takes into account the dictates of far-flung branches, from mathematics to physics, from algebraic topology, to neuroscience. Do you think that such broad multidisciplinary tactics could be the key able to unlock the mysteries of the brain, or do you think that more specific and “on focus” approaches could give us more chances? JLRC: Perhaps the term “consciousness” should be substituted for the word “brain”? Extensive biological knowledge of information processing in brains from organisms with only a few neurons to very large organisms with upward of ten to the ninth neurons exists. This information is generated from physical measurements. This information on the physical phenomenology associated with the physical methodology for measuring brain function (activity) is published in the open literature and available to any scientist who is interested in analysis of physical phenomenology. >From my perspective, the deep premise underlying the hypothesis presented here >is inadequate to describe the physical phenomenology of brain activity. >Perhaps this premise rests on the a priori Kantian notions of space and time >rather than the systematic categories of Aristotelian causality. At it’s root, my view is simple. Any abstract mathematical theorem has meaning only within the mathematical symbol system. Any model of physical phenomenology requires symbolic quantities of physical units of measure be associated with the symbolic mathematics. The meaning specified by the mathematical symbol is not the meaning specified by a physical symbol. Given the theory of quantum mechanics and the critical role that angular momenta play in the organization of brain dynamics, I would conjecture that it is conceivable that electro-dynamic equations akin to Feynman diagrams are needed to quantify brain phenomenon. Conceptually, one can speculate that such a hypothetical diagram for changes in angular momentum might take a conceptual form such as: A + B —> [ACB —> A’CB’] —> A’ + B’. where the alphabet symbols represent different collections of electrical particles.
