Neural Circuits, Microtubule Processing, Brain’s Electromagnetic Field—Components of Self-Awareness

Abstract

The known theories discussing the essence of consciousness have been recently updated. This prompts an attempt to integrate these explanations concerning several distinct components of the consciousness phenomenon such as the ego, and qualia perceptions. Therefore, it is useful to consider the latest publications on the ‘Orch OR’ and ‘cemi’ theories, which assume that quantum processing occurs in microtubules and that the brain’s endogenous electromagnetic field is important. The authors combine these explanations with their own theory describing the neural circuits realizing imagery. They try to present such an interdisciplinary, integrated theoretical model in a manner intuitively understandable to people with a typical medical education. In order to do this, they even refer to intuitively understandable metaphors. The authors maintain that an effective comprehension of consciousness is important for health care professionals because its disorders are frequent medical symptoms in emergencies, during general anesthesia and in the course of cognitive disorders in elderly people. The authors emphasize the current possibilities to verify these theses regarding the essence of consciousness thanks to the development of functional brain imaging methods—magnetoencephalography, transcranial magnetic stimulation—as well as clinical studies on the modification of perceptions and feelings by such techniques as mindfulness and the use of certain psychoactive substances, especially among people with self-awareness and identity disorders.

A Quantum-Classical Model of Brain Dynamics

“…The idea that electromagnetic resonance is the fundamental mechanism of communications among molecules was first proposed by Veljkovic et al, who also suggested that such a mechanism could provide a long-range effective communication [187]. At this stage, we believe that a unification of the EMF and Orch OR theories of brain dynamics is conceptually very probable [156].…”

“…Nevertheless, our analysis below can elucidate the fundamental quantum coherent properties of the microscopic EM fields invoked by such an approach. [150][151][152][153][154][155][156].…”

“…Although the TDCS-induced physiological mechanisms are not yet fully understood, it is assumed that its effects are based on long-term potentiation (LTP) and longterm depression-like (LTD) mechanisms [88,89]. Although the EMF approach was not originally related to QM when it was first formulated [9][10][11][12][13][14][15][16][17], a deeper quantum optical reformulation [90][91][92][93][94] cannot be excluded in principle.…”

“…According to quantum electrodynamic [93], a trapped photon may be considered as a virtual photon. Thus, it is difficult to disentangle the action of EMFs from quantum effects in the brain [94].…”
