Researchers at the Universities of Edinburgh and Cambridge say that most of the experiences can be explained by a reaction in the brain prompted by a traumatic and sometimes harmless event.
The researchers say that many common near-death experiences could be caused by the brain’s attempt to make sense of unusual sensations and perceptions occurring during a traumatic event.
Out-of-body experiences, for example, may happen when there is a breakdown in the brain’s multi-sensory processes, and visions of tunnels and bright lights could stem from a breakdown in the brain’s visual system caused by oxygen deprivation.
The new study also points to the effects of noradrenaline, a hormone released by the mid-brain which, when triggered, may evoke positive emotions, hallucinations and other features of the near-death experience.

wow, so 45 days since the last post. I apologize everyone, that's unacceptable. I will try to post an article or two during my study breaks.
