The conception of consciousness from Metaphysics to Quantum Biology: Critical review

The definition of consciousness and its essential characterizations, has been known over the centuries different interpretations, with different approaches and points of view, philosophical, neurological, psychological, biological and quantum. Since none of the successive interpretations in previous years it is still satisfactory and conclusive, the research continues towards more daring and abstract theoretical proposals.
In this article I am going to try to collect some of the various lines of research, exemplifying current trends, in the specialized literature on the subject.
The different articles are grouped according to the conceptions and theories that unite them, and are critically examined by showing the inconsistencies within each of them and the antithetical logical conflicts that exclude them from each other, leaving the original enigma still unsolved: what is conscience?
I have devoted a more in-depth examination of quantum theory and quantum biology on this topic, highlighting the inconsistency of fundamental assumptions, compared to the consolidated knowledge of fundamental neurobiological structures and functions.
