One of the research papers cited in this paper (link above) is entitled "Video Ergo Sum", which I think is unintentionally very insightful. In all the discussions and other adventures I have had concerning the nature of human awareness and its seat and source, the common denominator is that apparently non-material ability which takes on viewpoints, and by assuming them, perceives therefrom.
I suspect, on this basis, that the experiements described were essentially inducing the assumption of an OOB viewpoint. But doing it by confusing perceptics, on a impulsive or reactive-response basis, rather than as an elective ability.
I am far from persuaded that chemicals in strings and nets or organization can create an actual point of view from which perception occurs. And even further from persuaded that they can bring about perception itself.
