The main goal of my work is to search for the correlation between clearly determined quantum states located in the neuronal system with conscious brain functions, which allows us to identify the true essence of the human consciousness with these collective states. The state of art of this Quantum Neurology is too primitive and its development is yet initial, but the scanty knowledge of the physical perspective of consciousness is, or should be, stimulating for the physicists and above all it should not be a reason for desisting from further study.

Our proposals have the common idea of the quantum coherence of the many-body (collective) states (this point can be congruent with the PH model). These states have a well determined set of quantum numbers that can be recorded, and after reproduced by soft memories located in the skeletons of the neuron cells. The second idea is to analyze the mechanism for the appearance of these quantum coherent states, which can be generated via the interactions with external signals coming from sensorial windows. The causal formation of these states with the external interactions and their description is another objective of this work. Finally, the possible survival of the coherence of these states beyond room temperature of the human brain in normal conditions is an argument which gives support to these models as solutions for understanding the neuronal functions. In addition, these models clarify certain obscure points about quantum coherence which produced a lively debate between Tegmark’s group and Hameroff’s group.

The tubulins are the elemental components of the microtubules that, in turn, are the main structures of the skeleton of the neuronal cells. These tubulins form lattices similar to some organic crystals. In these lattices, the existence of magnetic order provoked by the spin orientation of the electronic components can be possible. The oscillations of these magnetic lattices constitute magnon coherent states whose properties are similar to the coherent light radiation. The coherence of these states remains even with high temperatures, therefore, they can survive in the brain, their record can be correlated with a mind action and consequently, they can be reproduced when the external interactions that initially provoked its appearance is repeated.

In a latter section of this work, I comment the possible consistence of our models as well as the coherence and possible agreements (and disagreements) with other previous theories. In any case, I consider that my achievements and advances in the physical description of the human consciousness via the formation of coherent states are very modest, at least for the moment. However, I think that quantitative analysis of those above cited correspondences between microtubule states and mind actions can allows us to test philosophical concepts such as the supervinience and others, which might constitute substantial advances in the physical knowledge of the consciousness.
