NPR featured a critical care physician, Dr. Parnia (@ Stony Brook University). http://m.npr.org/news/Books/172495667
"Resuscitation medicine is now sometimes capable of reviving people after their heart has stopped beating and their brain has flat-lined." Dr. Parnia studies resuscitation medicine. He made a few not very clear (at least to me) comments.  For example: "And so what our discoveries have started to do is to question the way we consider the relationship between the human mind, what is classically been called the psyche or the soul, and the brain itself. And it may be that the human mind, consciousness or soul may be able to function when there is no brain function at all. "
I say this with due respect to Dr. Parnia and his work: Stony Brook's Web site lists his qualifications as an internal medicine physician by training with specialty in pulmonology, critical care, and sleep medicine. However, Dr. Parnia's comments are very much related to neoroscience.  I am wondering, if any neuroscientist who might be familiar with Dr. Parnia's work has commented on his conclusions.
