From The Morning News, "The Heretic," a profile of psychedelic pioneer and researcher James Fadiman. From the article, "If certain of these molecules connect with our serotonin receptors like a key in a pin tumbler, and open a door to extraordinary vistas, why shouldn’t we peek?" In the post Psychedelic Trip Guides I covered his great Psychedelic Explorer's Guide and free online Entheoguide. And on his personal website it looks like there are a number of videos that may be worth checking out.
From the Kavli Foundation, "The Fantastic Plastic Brain" discusses the remarkable adaptivity of the human brain, even into old age. "There are clear advantages to getting the brain wired up in the right
fashion early in development, but still there are a number of Olympic
medalists who didn’t begin their sport until they were well into their
twenties. Maybe we learn a bit slower, but with persistent training and
practice we can overcome this limitation or lack of advantage we didn’t
get early on."
From Stillpoint Integral, an article on Ego Development framed within Ken Wilber's AQAL map of human development, by Susanne R. Cook-Greuter. This maps development from self-centered and impulsive all the way up to unitive.
