Consciousness is the state of mind that allows us to realize our own existence, that of other people and the things that happen in the world in which we live. It is created by millions of neurons that reside in the temporal, parietal, and occipital lobes of the brain, that is, in the posterior cerebral cortex, a knowledge that, sooner or later, can make possible the recovery of conscious state in those who have lost it due to accident or illness and lie unconscious in a hospital intensive care unit.
