Abstract

The questions concerning “who we are”, “where we go to”, and “where we come from”, preoccupied the humanity from immemorial times. During the last few decades, with the accelerated improvement of the investigation methods and of the advanced successful interventions allowing the life salvation, there have been reported some attempts to correlate the psychic phenomena with the body status by the recuperation, analysis and explanation of the symptoms recorded during the near-death experiences. Such special situations, in which the heart and the brain, the support of mental activities, cease their activity, has become a fundamental tool to investigate the consciousness associated phenomena during the arrest status of the fundamental processes of the life. The fundamental question actually is whether consciousness really continues to exist even if the body has ceased its function by stopping the heartbeat and brain support activities [1,2]. An answer to such a question goes toward even further questions: can there be “life” beyond the death [3]? This exciting question includes also several aspects: what is consciousness and which is its nature [4]? Could consciousness exist as a disembodied entity? To answer these fundamental questions of existence, the collaboration of several disciplines such as neurology, psychology, medicine, biology, pharmacology and also physics, to call only the most important of them, is necessary, the geriatrics finding suitable responses within the multidisciplinary researches to its various questions related to the life prolongation and the improvement of the life quality. Within such a context, it was recently developed an informational model of consciousness, which can offer response to the above questions, based on the last discoveries of the quantum physics and cosmology [4,5].
