If, indeed, we are not material beings, we still manifest through the brain while we are in this biological form. Hence, neural correlates remain of great interest, even if they are not causes. In that case, Chalmer's Hard Problem of consciousness changes from "How does consciousness arise from biology?" to how does "consciousness interface with the biology?" (Part of the consciousness-holosoma problem coined by Massimiliano Sassoli di Bianchi).
To begin to answer this matter, at the International Congress of Conscientiology (Consciousness Science) speaker Brenda Dunne will apply insights from the Princeton Engineering Anomalies Research (PEAR) lab and Wagner Alegretti will share the latest results of his studies employing fMRI to detect chi and to study the neural correlates of the vibrational state. Vannini and di Corpo, on the other hand, draw on the principle of syntropy for mathematical and physical support for the organizing ability of living beings in a universe dominated by entropy. Trivellato and others present other works related to this "life force," "chi" or bioenergy.
In this blog article, IAC's Nelson Abreu argues that the OBE has not been shown to be produced by the brain. http://iacblog-english.blogspot.com/2013/06/ask-iac-1-isnt-obe-caused-by-brain-part.html
Here, Wagner Alegretti gives a sneak peak of this first pilot study on vibrational state which he has discussed at Florida International University, universities in Brasilia and EarthRise Retreat Center at the Institute of Noetic Sciences.
In a seminal essay, Dunne and Jahn summarize 3 decades of research at Princeton and what it may mean for the nature and science of consciousness and its role in physical reality. The essay went on to inspire the Filters & Reflections anthology, which features a chapter by IAC's Nelson Abreu who relate OBE's and bioenergy to PEAR's research findings and theoretical models.
In this blog essay, IAC's a Nelson Abreu speculates on the consciousness driving biological evolution and neural activity, drawing on the work of Alegretti, Dunne/Jahn, Sheldrake and others - no doubt a hot topic at the ICC.
