"There is now convincing evidence to challenge the current theory that consciousness can only exist inside the brain - and if you can have consciousness without associated brain function, that is enormously important for our understanding of the mind," he said.

For his latest research, 60 patients at Southampton General Hospital’s coronary care unit were interviewed after heart attacks had left them temporarily brain-dead. Seven reported near-death experiences - defined by characteristic features such as a feeling of leaving your body, going through a tunnel and entering an area of "love, bliss and consciousness".

Dr Peter Fenwick, renowned neuro-psychiatrist, will discuss his research on the near-death experience.D


Dr Fenwick said: "If the mind and brain can be independent, then that raises questions about the continuation of consciousness after death. It also raises the question about a spiritual component to humans and about a meaningful universe with a purpose rather than a random universe

."We cannot keep the life we have on the Earth realm, not our possessions or attachments or relationships. What we can keep is our memories and our feelings of what we have integrated into our heart of hearts from the experience of being here, plus the love we have shared with others." - P.M.H. Atwater

 The expansion of mind in NDEs have happened to many people

The following NDE descriptions of consciousness expansion supports the theory of consciousness described above by Stanislav Grof. It theorizes that the brain acts as a reducing valve of cosmic input to produce consciousness. At death, this reducing-valve function ceases and consciousness is then free to expand. The following NDEs support this:
a.  "I realized that, as the stream was expanding, my own consciousness was also expanding to take in everything in the Universe!" (Mellen-Thomas Benedict)
b.  "My mind felt like a sponge, growing and expanding in size with each addition ... I could feel my mind expanding and absorbing and each new piece of information somehow seemed to belong." (Virginia Rivers)
c.  "In your life review you'll be the universe." (Thomas Sawyer)
d.  "This white light began to infiltrate my consciousness. It came into me..It seemed I went out into it. I expanded into it as it came into my field off consciousness." (Jayne Smith)
e.  "My presence fills the room. And now I feel my presence in every room in the hospital. Even the tiniest space in the hospital is filled with this presence that is me. I sense myself beyond the hospital, above the city, even encompassing Earth. I am melting into the universe. I am everywhere at once." (Josiane Antonette)
f.  "I felt myself expanding and expanding until I thought, "I'm going to burst!" The moment I thought, "I'm going to burst!", I suddenly found myself alone, back where this being had met me, and he had gone." (Margaret Tweddelll)
g.  Susan had an out-of-body experience where she left her body and grew very big, as big as a planet at first, and then she filled the solar system and finally she became as large as the universe. (Susan Blackmore)
