Quantum consciousness and a-quantum consciousness: a hypothesis for interpretation
Faculty of Human and Technological Sciences, L.U.de.S. University, Lugano, Switzerland
Head: Prof. Rodolfo Paoletti, rector
Beyond the conviction that the origin of major depression can be found in genetics (1-3) a biomolecular mechanism could be hypothesized, based on what emerged from the studies on platelet fatty acid composition in humans (normal and depressive subjects), which allowed depressive disorder (4) to be classified using an artificial neural network (Self Organizing Map – SOM), (5) as a mathematical tool, because of the complexity of the membrane dynamics.
Rapid changes in membrane lipid composition or in the cytoskeleton could modify neuronal signalling. With the knowledge of having found something that could have implications for the understanding of some aspects of psychiatric disorders, a very suggestive hypothesis was built as summarized in Figure 1.
Fig. 1. Molecular depression hypothesis.
Figure 1 describes the molecular depression hypothesis according to Cocchi and collegues, (4) Donati and collegues, (6) and Hameroff and Penrose. (7, 8) The membrane viscosity can modify the Gsα protein status. The Gsα protein is connected with tubulin. Tubulin, depending on local membrane lipid phase concentration, may serve as a positive or negative regulator of phosphatidylinositol bisphosphate (PIP2) hydrolysis, such as Gsá protein does. Tubulin is known to form high-affinity complexes with certain G proteins. The formation of such complexes allows tubulin to activate Gsα, which, in turn, can activate protein kinase C and fosters a system whereby elements of the cytoskeleton can influence G-protein signalling. Rapid changes in membrane lipid composition or in the cytoskeleton might modify neuronal signalling. We have hypothesized that through this mechanism it is possible to modify the state of consciousness and that it is measurable through gamma synchrony EEG (9).
Much time is spent today on research to identify those mechanisms that are considered still unknown, not yet discovered, but ready to be captured by some great intuition. The point is to understand the mechanism of signalling, gene expression and the levels, perhaps even more submicroscopic than those perceived now, of cell communication (10).
This work, in particular, aims to raise the issue of relations between a biological event and a state of physical consciousness, as appears likely from the evidence, so far obtained, using quantum calculation, and that aspect of consciousness that governs sensation.
Figure 2 presents a possible interpretation of a-quantum perception when compared to physical perception.

„The boundaries of your soul you will not ever find, as you walk through its streets, so deep is its logos.” (Eraclito, fr. 45; Gabrielli 11)
The powerful Heraclitean fragment could serve as a warning to those who normally contribute only to entire human biology, quantitative determinations of neural nature, to mere biomolecular temporality. Due, however, to the inability to calculate, to give quantum substance to the time lag between what determines the feeling and its realization, one can open fruitful avenues of research within which the possibility of a more widespread abyss of consciousness is not quantifiable. In this context it would be interesting to consider the possibility of a pre-sensitive phase, we might call original intuition, or an unmeasurable dimension, not affected by psychic correlations, on whose mysterious nature (root mu, Greek muein: „putting a finger in front of the mouth and being silent”), at least for now, the philosophy is requested in person.
