LSD and psychedelics are the next frontier in science IMHO.
And I don't mean just neural science, psychology or psychiatry.
It seems that these substances hold the key to how the brain "produces" reality and that could open doors to areas such as computer-brain interfaces, transfer of consciousness, fully immersive "life-long" virtual reality and so on.
But that's just peanuts.
There's the social aspect - psychedelics have had a strong influence on millions of people when they became popular in the '60s, shifting their worldview, which in turn lead to new directions in music, art, film, literature, science and society in general.
Then there is the "ecological" aspect. Many people report "feeling one" or "connected" to everything including other living beings when tripping on psychedelics.
That metaphor persists after coming down and many people become aware of their place in nature, what they eat, how they treat animals and plants and eventually other humans.
"Flower power" might just be what's necessary to curb humanity's most stringent problems, such as "climate change".
"Make love not war" hippy slogan will also help given how armed the world is right now. I would add "use condoms !" to it though - there's too many of us here already! :).
The MRI images are a confirmation of the "mind expanding" term used so often in conjunction with these substances.
Maybe "mind expansion" is what's needed in order to combat the "mind shrinking" that is so beneficial to the few, who, with their ignorance and greed, are about to run this ship into the ground.
I'd love to see more research, a lot more research with these substances.
Understanding these links is very important, because right now there is a new, larger, global wave of psychedelic use which is unprecedented.
