Interesting material, tele.
So I wonder why psilocybin would cause a decrease in traffic between different areas of the brain? As I understand things, the psilocybin (well, actually it is psilocin by the time it gets to the brain) molecule has a similar shape to the neurotransmitter serotonin. It thus activates serotonin receptors that would not normally be activated as much. Not sure how this could cause a decrease in communication between various parts of the brain, unless maybe it serves as sort of a distracting "noise"?

This is not realy new information. It was known long before that psychedelic´s such as DMT, mescaline and LSD, diminish brain activity in especially the neo-cortex, and often activate brain activity within the limbic system. It's not so clear though, that diminished brain-activity automatically means that your mind itself is being diminished as well, as the first article suggests.

Poly, clarify this if I'm wrong, but by diminished brain activity you mean diminished blood flow right? Most (all?) of what I have seen has made this 'dark brain hole' hypothesis from blood flow imaging. And yeah I see how this could correlate to reduced brain activity in that region...but I don't think it's a direct 1:1 correlation. Peace If your religion, faith, devotion, or self proclaimed spirituality is not directly leading to an increase in kindness, empathy, compassion and tolerance for others then you have been misled.

But it's true that it's probably just an indication of how active some regions of the brain are, instead of 100% proof.

Surely by deactivating a section of the brain the other sections will be able to run more efficenttly, just like disabling unnecassary processes on a computer?
Multitasking's a bitch.
