Can an unconscious person be aware of his surroundings? Part 2 (Teacher: Michael)

He believes that when one billion microtubules attain the same chemical state for 500 milliseconds, this causes a quantum "event" in the brain and that these events up our thoughts. We still cannot measure brain "consciousness" but Penrose's theory suggests a way that this may possible in the future.

The Lancet article suggests that a person may have some awareness of his surroundings even though he is unconscious. Researchers in Holland interviewed 344 patients, who recovered, from a coma after their hearts had stopped beating for up to" five minutes due to a heart attack. Forty-one of these patients that they able to recall the period of time when they unconscious. They aware that they "dead" and 15 had an experience that they floating above their "dead" body, watching medical staff trying to resuscitate them.

One particular patient correctly able to describe the room he in when he deeply unconscious and a nurse his dentures and them in a particular drawer - the nurse later confirmed these details. In another report, a woman accurately related events that occurred when she unconscious and a brain wave test (electroencephalogram). no brain activity.

It has suggested that these phenomena are either tricks of the memory or psychological responses to a very traumatic situation. This does not explain however, how patients could register details during a period when they unconscious. Further research is going on to confirm that this really does occur, but if confirmed, it suggests that patients who appear to unconscious might still have some "conscious" brain awareness. How this could occur cannot explained by our current knowledge of how the brain works.
