I have already provided scientific opinion on NDE's in another thread. Here it is again...

NDEs are an intriguing and relevant phenomenon, the nature of which is still under debate. Their apparent trascendent tone may wrongly lead one to take them as clues of an afterlife, glossing over the neurobiological mechanisms involved in producing them; on the other hand, a prejudicial refusal of facts that appear trascendent or paranormal might wrongly lead to neglecting them due to their apparent incompatibility with the widely accepted materialistic view of the world and known scientific laws. Both these stances may be harmful sources of opposite errors, the former leading to belief in non-existing “facts,” the latter to denial of existing ones.
As already discussed, the idea that NDEs are the mere results of a brain function gone awry looks to rely more on speculation than facts (Mobbs and Watt, 2011) and suffers from bias in skipping both the facts and hypotheses that challenge the reductionist approach
In conclusion, NDEs are an intriguing and still misunderstood phenomenon, challenging the heart of neurobiological axioms..
it is only worth emphasizing that spirituality is a faculty of the mind, and, as such, it is independent from any theological or doctrinal view and can be scientifically studied [see the outstanding recent books by Kelly et al. (2007) and Walach et al. (2011)]. It is now time to remove the ongoing cultural filters and include consciousness, spirituality, and the highest mind expressions in neuroscience in a free, secular, and scientific perspective to overcome old prejudices.
Here it is only worth mentioning how the relationship between mind and brain, the so-called “hard problem,” is still an unsolved problem (Chalmers, 1995, 1999; Rudrauf et al., 2003; Ibanez, 2007). The whole of data here reported indicates an increasing need for a broader scientific approach to consciousness and other non-ordinary activities of mind, including those belonging to the suspicious areas of transcendence and spirituality, with their still misunderstood physiology. This might be the case with NDEs as well, where taking a priori the content of such awkward experiences as exclusive expression of brain pathology and worthless epiphenomena of brain circuitry might lead to misleading results.
